For those who havent watched the recent trailer and development of final fantasy versus XIII,heres some juice for you 
Taken from wikipedia----
Final Fantasy Versus XIII (ファイナルファンタジー ヴェルサスXIII, Fainaru Fantajī Verusasu Sātīn?) is an action role-playing game developed and published by Square Enix exclusively for the Sony PlayStation 3 video game console.Alongside Final Fantasy XIII and Final Fantasy Agito XIII, the game is a part of the Fabula Nova Crystallis Final Fantasy XIII compilation. Unveiled at E3 2006, the game focuses on a mysterious protagonist who is the last heir of a dynasty ruling over the only remaining city to control crystals. Under unforeseen circumstances, he makes a stand against marauders seeking to take the crystal as their own.
Final Fantasy Versus XIII is, according to its developers, a wholly independent story unfolding with different characters and a different visual design. Although it is set within the same Final Fantasy XIII universe, it is unrelated to any other entry within the compilation and is thus neither a sequel nor a prequel to any other entries in Fabula Nova Crystallis: Final Fantasy XIII.
GAMEPLAY
Unlike Final Fantasy XIII, there is scarcely any information surrounding the gameplay and battle system of Final Fantasy Versus XIII because no formal footage has been shown by Square Enix of the gameplay online or within video game magazines.
Within recent Japanese gaming magazine interviews, Tetsuya Nomura has stated that Versus XIII's gameplay will be a realistic derivation of Kingdom Hearts's battle system with some elements of a third-person shooter aspect similar to Square Enix's Dirge of Cerberus. Nomura has also stated that the game will depart from the light and magical aesthetic of his previous directorial games (i.e. Kingdom Hearts) and opt for a darker, bleaker world that is intended to counter previous Final Fantasy installments. In formulating a realistic world, Nomura has stated that he wants the characters to be "believable" and thus realistic. As a testament towards his desire for realism; in the PlayStation Premier trailer, in contrast to previous Final Fantasy titles, Versus XIII had a greater display of graphic violence with an instance of blood.
Nomura has also stated in Dengeki PlayStation that he aims to create previously unseen "tricky" battle sequences, reminiscent of the CGI film, Final Fantasy VII Advent Children.
PLOT
Very little information regarding the plot of the game has been revealed since E3 2006; however, Square Enix representatives have commented that Versus may be the darkest Final Fantasy game yet.
Final Fantasy Versus XIII involves Noctis Lucis Caelum, the last heir to an isolated nation, which holds the last Crystal protected by kings. Its isolation is due to the city's resistance to protect itself against invading heretics.The game has been said to initiate at the "clearing" of a long Cold War between warring nations that revolved around the crystals.
CHARACTERS
The protagonist of Final Fantasy Versus XIII, Noctis Lucis Caelum (ノクティス・ルシス・チェラム, Nokutisu Rushisu Cheramu?), is the last heir to the Caelum Dynasty, which rules over the only remaining city-state to control the Crystals. He attempts to protect his city-state against those who seek to conquer it and take the Crystals by force. Nomura has compared Noctis's family to the modern-day Japanese mafia.[10][11] The color of his eyes have been shown to change during battle; his eyes have turned from blue to crimson. Tetsuya Nomura stated that the color changes are both intentional and significant.[9] Noctis's full name is Latin for "Light of the Night Sky,"[12][13] and his nickname is "Noct".[13]
The weapons that Noctis wields are multiple, ranging from swords, spears, and lances to a gun. He can control them with telekinesis (through the power of the Crystal), using them for both attack and defense. Nomura has stated that each weapon will have a different usage and is not directly limited by normal standards of attack; for instance, some weapons will also be usable as shields (as seen in the trailers).[14] He also has the ability to teleport or to suddenly move at a high speed, though it is unknown what role this skill will have in the actual gameplay.
Noctis's personality is different from any other character in the Final Fantasy franchise (including that of Cloud Strife of Final Fantasy VII and Squall Leonhart of Final Fantasy VIII), one that Nomura had wanted to try out for a long time.[15] In the past, protagonists were given strong personalities while the distinctive ones were delegated to the supporting cast, but Nomura states Noctis's idiosyncrasies mark a departure from this tradition.[15] Although his character is said to be hard to define given his complexities,[13][16] a good measure of his personality can be sensed from his first meeting with Stella.[17] Despite his cold and unsociable appearance, Noctis hides his shyness underneath a fa?ade of coolness in front of him.[17] However, he acts more openly around his three friends, usually smiling,[13][16] a testament to Nomura's statement that "he is not the least bit a silent, gloomy little boy."[15]
Stella Nox Fleuret (ステラ・ノックス・フルーレ, Sutera Nokkusu Furūre?),[12][13] shown to be a young woman with blonde hair, is said to be the princess of the Fleuret family of the country Tenebrae (which is Latin for "darkness"),[11][17] and an enemy to Noctis, though her allegiances are under suspicion.[citation needed] Stella Nox are two Latin words that would mean literally, albeit incorrectly inflected, "Night Star."[citation needed] Fleuret is the French name of the fencing foil, a direct reference to Stella's weapon of choice, a rapier. Like Noctis, she is able to materialize weapons from thin air, as she is shown summoning her rapier from a rune similar to one used by Noctis to summon his sword, though Stella's rune is golden while Noctis's is blue.
Like that of Noctis, a good measure of her personality can be sensed in her first meeting with Noctis.[17] For instance, in their discussion about the power they share (defined as a special ability to see the "light") and its connection to an old legend,[11] Stella is very open about the matter while Noctis seems reluctant to talk about it, suggesting that they keep it a secret.[17] Stella is described to be ladylike and extremely polite,[18] but direct in her manner — a reflection of her proper but strong upbringing.[11][17] She acts according to her beliefs, and doesn't shy away from problems.[11][18] Nomura states that she will be the first to stand out from other female characters in the Final Fantasy franchise,[18] although it is not specified how.
Noctis has three companions who have been revealed in the video game magazine Famitsu.[verification needed] The first of these characters is a man with light brown hair and glasses who is seen wearing a suit and driving the protagonist's car. The second character is a bulkier man with dark brown hair and a scar on the left side of his face. The third character is a young blond man carrying a shotgun. These three people are Noctis' friends; they speak casually and amicably with him, and they also accompany him during his travels.
Another character, wearing all white (possibly a symbolic contrast to the protagonist's darker clothing, which may imply another character foil), has been introduced as well. This character is seen facing off with Noctis in a building near his castle, where they cast spells at each other, implying that they are enemies.[citation needed]
Mysterious soldiers have been featured in the trailers as well. These unknown warriors wear medieval-styled armor but also carry assault rifles resembling modern automatic weapons. It is known that some of these soldiers are marauders trying to take the crystals as their own, as many of them attack Noctis.[citation needed]
Another man, older than Noctis and dressed in a business suit, appears sitting at the head of a long table as a chairman during a meeting with several other men. He is discussing in a business-like manner with other people at a grand hall with cathdral like settings.
DEVELOPMENT
Final Fantasy Versus XIII began development as early as 2003, two or three years prior to E3 2006 in conjunction with Final Fantasy XIII, after the PlayStation 3 Final Fantasy VII Technical Demo was completed.[19] Led by Tetsuya Nomura, the game was developed by the team responsible for the Kingdom Hearts games as well as Final Fantasy VII Advent Children. As with Final Fantasy XIII, development initiated on the PlayStation 2 but was later shifted to the PlayStation 3 when the development team determined that the PlayStation 2's hardware would not suffice for the "visual expression" that the team had initially decided upon and that the single DVD format did not have the adequate storage requirements. As such, most of the development was restarted on the PlayStation 3.[19] Versus XIII was considered unsuitable as an iteration of the Final Fantasy series due to the concept and thinking behind the game's plot and structure.[20]
Along with Final Fantasy XIII, the game utilizes the Crystal Tools engine - an engine specifically designed by Square Enix for the seventh generation of video game consoles. However, in early 2007, Square Enix had announced they had licensed Epic Games' Unreal Engine 3 for use in their future next generation titles, like The Last Remnant. Some speculated that Final Fantasy Versus XIII would be developed using the Unreal Engine 3, however, Square Enix has stressed the White Engine - later renamed Crystal Tools - would be used in Final Fantasy XIII and Final Fantasy Versus XIII in the Fabula Nova Crystallis compilation.[21][22] It was announced that the game would use the PlayStation 3's motion-sensitive SIXAXIS controller.[14]
Reports of June 2008 that Final Fantasy Versus XIII had been put on hold so that the Versus team could assist work on the main title, Final Fantasy XIII, were later debunked by Square Enix, stating that this was a mistranslation of an interview from Famitsu[23] and misinterpretation of the article, and that both games are moving along at their original schedules; occasionally, Versus developers assist with Final Fantasy XIII development.[24] Square Enix announced at its DKΣ3713 party in August 2008 that the demo of Final Fantasy XIII, as well as new trailers of Versus XIII and Agito XIII, would be released in the highly-anticipated Final Fantasy VII Advent Children Complete Blu-ray Disc.[25] Square Enix announced the release date of the new Advent Children Blu-ray release to be some time during March 2009 (later changed to April 16) and asked fans to disregard previous release dates.[26] Famitsu released a 50-minute DVD entitled "Re: Riplai" on December 13, 2008 including trailers from the Fabula Nova Crystallis series and other Square Enix titles.[27]
