that's a damn good point. creativity is certainly restricted with less options... i'm more talking about motivation in games... but either way. the freedom to be creative is fantastic, if you ask me.
You can't simply throw in symbolic art into any game. It needs to work with the creative direction, or it will clash with the creative direction. So no, there are no games with symbolism JUST from the art side.
it's weird... it's not like it makes you/me more creative. i feel just as creative sober. but i do find it easier to express myself artistically, and musically, under the influence.
