Katamari Damacy!
Anyone with a modern Sony console should run out & buy whichever titles in the series are available in their region (We ♥ Katamari on PS2 everywhere; Katamari Damacy on PS2 and Me & My Katamari on PSP in USA/Japan).
That means you, mister Zak33.
These games aren't just fun, they aren't just good, they're an experience that no psychotropic substances can compare to. Hurry hurry, before it sells out!
