Todays replayability: DLC and online multiplayer.
WRPG's: Multiple endings resulting from the choice trees.
Action Adventure: Lairs and areas that are unlockable once you attain keys from the first playthrough. Character buffs, etc.
Fighting games: Stories with elaborate endings for each character w/online multiplayer.
Racing: Various new tracks and experiences unlocked so you can dig deeper into the game.
I could say more, but in truth the whole point is about making sure the game is so good that replayability becomes an option. I've even seen people replay games just because they were so good that they had to replay it again on a harder setting and funny enough they got two different experiences off of the difficulty alone.
