[link]SUPERHOT[/link]. Incredibly short Matrix simulator but incredibly memorable and fun fun fun. Despite it being about ten minutes long, it's probably the most replayable singleplayer experience ever. They're releasing a full game on Steam some time in the future that I really want.
The Last Stand series. Pretty simple zombie game. The first one is defending your base against zombies while trying to find supplies, survivors, better weapons while maintaining your base. The second one is more of the same, but with actual challenge and variety. The second one is more of a roguelike, in my opinion, because of the length of your average game, the multitude of different routes you can take to the end, and a bit of luck. The third one is a sidescroller adventure shoot-em-up with an incredibly impressive world (for a Flash game) but admittedly menial gameplay. I think the second one is the best, very replayable.
