For me it's probably Fez. Just amazing.

gog.com have loads of good & classic computer- and some really cool Indie games. And the prices are quite fair also. There are great sales pretty often too (at least on every weekend).
You don't lose anything if you sign up there; you just get 5 free games ;)
For me gog.com is the best site to get my digital and DRM-free versions from many of my favorite classic titles 8)
Most, if not all LucasArts' point & click -adventure games have a brilliant story.
I would recommend to try Day of the Tentacle, Monkey Island 1 & 2, Full Throttle and Grim Fandango; cool cartoonish graphics with tons of laughs and great storyline.
Even thought Diablo has an awesome Soundtrack, NIN's Quake OST is a clear winner for me. Probably the very best (game)soundtrack there is...
Actually, Quake OST and The Downward Spiral are the albums, that made such a big NIN fan 8)
This is one of those games that I had to stop playing because the lack of time. Very addicting game indeed.
It's really annoying sometimes that there are tons of superb games waiting for you to play, but there's not nearly enough hours in a day... :/
The Walking Dead game is superb! Dead Space series is scary as hell also, especially the first one.
And if you want real scares from a horror adventure game (for being so crappy), get Roberta Williams´ Phantasmagoria from gog.com ;)
