Trippiest game you've ever seen?
Basically games that made you question what kind of drugs game developers or art designers were consuming in worrying amounts.
For me, probably Rayman 3: Hoodlum Havoc. Having downloaded for HD a few months ago, I realised just how fucking weird everything looks, sounds, acts, moves and throws right in your face. I mean, by god, they have entire levels dedicated to mind-altering illusions or some shit that you have to not look at because it's a platforming section, as if they totally know just how hallucinogenic they look. I've never seen so many colours in one game...
What about you guys?
