1: Journey

While the story is simple, it still has a lot of depth and leaves much room for interpretation. Not only that, it is told entirely without words, creating a massive emotional impact with visuals, music and subtle body language alone. It's also the first and only game that ever made me cry.

2: Planescape: Torment

Exactly the opposite of Journey, this game is extremely text-heavy. In printed form it would be a book heavy enough to kill a goat with. Yet the writing is so excellent and creative that I didn't mind reading for weeks on end in a foreign language... it feels as if each of the dozens of minor NPCs in this game has a character and backstory more compelling than most protagonists in other games. Not to mention the amazing main storyline about which I could ramble forever...
Also, one of your party members is a floating, burning, eternally tormented, masochistic pyromaniac who wants to kill everybody. How awesome is that? (Ignussss wishesss to burrrnn......)

3: Psychonauts

You're playing a boy named Razputin who's staying at a summer camp for psychic kids and who has to defeat a brain-harvesting dentist by exploring the subconcious minds of various lunatics. Also there's a level in which you grow to godzilla-size and terrorize a city of talking fish. Need I say more?
