As of now, I own:
- Deep "2FREAKNHARD" Dungeons of Doom
- Shadow "most monotonous TPS ever" Gun
- Rage "This stuff is addicting!" Runner
- Polarity A.K.A. "throw boxes around and solve puzzles!"

I'm stuck in DDD and finished both Shadowgun (with its buggy as hell add-on) and Polarity, so I'm planning on buying something else - maybe Sine Mora or Clark.
