Overkill sounds good for someone with a premium on free time.
If you're into 3D Sonic, i'd also recommend Sonic and the Black Knight. Few missions in that game take more than a couple minutes, so its easy to play in bite-sized chunks too.
Of course, if you're the kind who thinks Sonic should stay as he was, then stay far away from Black Knight.

Monster Hunter: pissing me off since 2010.
