Btooom! is in the game genre, but it's set in the real world instead of virtual reality. SAO with explosives instead of swords and a lot more mature content. I thought it was good, but it ended kinda abruptly after Episode 12 (dunno when or if a second season is coming).
Durarara!! has a little more complex storyline. Bunch of different residents, all psychopaths in their own way, in a city with gang activity and some supernatural happenings. The main character is supposedly Celty, whose supposed to be like a modern rendition of a headless horseman, but the screentime's divided so evenly between them all that it's hard to tell.
It's one of my favorite series. Lots of hilarious moments, and the cast is one of the best of any anime in my opinion

The dub and sub are pretty even performance-wise, but the dub is a lot more fun to listen to in my opinion.
