I just started Sword Art Online and I thought of a simple way to beat the game.
You take groups of 50 or 100 or so based on however many players were there. Have them train on level one until they're higher levels like 20 or so and then move up to level 2 after giving advice to the next group. Then they do the same on 2 while the new group levels up on 1, new group goes up before first group leaves to make sure the level and skill was high enough to make it and get advice for the new level from the first group. Then keep repeating until the last group from level 1 reaches the last stage before 100. Have everybody else wait at 99 for that last team to make it there then everyone who survived takes on lvl 100 at the same time. Unless the final level is an all the people who make it there vs each other 1 winner type deal.
