If you're into fighting games at all, I highly recommend Super Street Fighter IV. Sit down, fight a couple of online fights, and relax. No unlocking necessary; all the characters are at your disposal at the get-go. The game is just plain fun, and it really shows off how a lot of games these days lack the ability to just show the player a great time from button-on to button-off without including busywork or downtime of some kind. Best part: the game brand-new is half the price of most other newly released titles.

Then again, if you're not a fighting gamer, playing and losing online can get very frustrating.
