How often do you go for the smaller downloadable games? I like them to pass the time or when I'm not in the mood for a 15-hour committment.
Some recommendations from PSN -
Mushroom Wars - Cute real-time strategy with frenetic pacing.
The Last Guy Zombie apololypse played from a view that looks like Google maps. Rescue survivors and bring to safety. Oddly this game feels a lot like Pac-Man. Speaking of which...
Pac-Man Championship Edition DX - Better than a cup of coffee in the morning. Reworking of the original, adds puzzle elements and faster gameplay.
Dead Nation - Excellent zombie game that plays like Smash TV. Perfect atmosphere.
Pixeljunk Monsters - Solid tower defense game.
Pixeljunk Shooter - Interesting shmup where you manipulate different fluids to solve puzzles.
+1. this is very interesting.
