I'd Chip in with The Void. http://en.wikipedia.org/wiki/The_Void_(video_game)Nenad said:I heard there are older games that deal with philosophy. I don't know any, so can you recommend me some? Except PS:T, played that.
Quick Synopsis
'The game is about a soul that accidentally lingered in the Void, before absolute death. The Void is a purgatory-like place, in which the most valuable thing is Color, a liquid that represents lifeforce. Color is scarce and famine is a usual thing for its dwellers ? beautiful naked Sisters and deformed monstrous Brothers.
Color is a universal resource in the game, at the same time it is the hero's health, armor, stats and ammo. With the help of Nameless Sister, the soul finds out that there is a way to escape and be reincarnated again on the surface, but in order to do this the player must disguise himself as one of the Brothers and eventually confront them.'
If you can get used to the Difficulty, odd game play and occational Nipple, you will be in for a real treat if you what something to really make you think about the concept of the afterlife and the Ego.
