The Dig- an awesome graphic adventure from Lucasarts. Was originally going to be a movie.
Loom- a cute little graphic adventure game based around musical drafts.
Uru: Complete Chronicles- third person spinoff of the Myst series, but still fun nonetheless
RealMyst- remake of the first person graphic adventure classic

Hoping to get Riven soon.

By classic, what do you mean specifically?

Max Payne
Knights of the Old Republic
Jade Empire
Dreamfall
Jet Set Radio
Psychonauts
SEGA Genesis Classics (Obviously. It says classics right in the title.)

Star Wars: Dark Forces. It came out in the mid-90's so I assume it qualifies as a classic.

Planning on getting Dreamfall, although I might want to get a game controller first.

Indiana Jones and The Fate of Atlantis

Quite a few mostly from the megadrive bundles, if its retro PC games you want then gog.com is definitely worth a look just found out about it recently, has a ton of older PC games not found on steam like theme hospital, descent, the populous games and so on.

Dreamfall has a surprising amount of vulgarity in it, but if you can get past the language it's an awesome game, probably my favorite adventure game. So far, I've only played it with a controller. I'm not sure how it would handle without one.

@Reala Oh man. Witcher 2 is on sale for less than I paid for it on Steam--and on gog it's DRM free! >:[
I have yet to download anything from gog but I've been meaning to give Planescape Torment another go and maybe Alone in the Dark: The New Nightmare.

I got Mario.

On Steam? When did Nintendo authorize that?

Anyways, I don't have much just LOOM, The Dig, Psychonauts, and maybe a few others that I'm not sure on the dates.

I'm aware of the language in Dreamfall. I've played through The Longest Journey, and I loved it (especially the complex universe it develops).

I noticed how the game bombards you with language in Stark and then eases up in Arcadia. They did a good job of building two worlds in that game. Crow is the best.

Amen to that.
