Dark Souls would be amazing on steam if it doesn't have GFWL.

To The Moon (it's a matter of when, not if :D)

I want the Legacy Of Kain series. I don't know if you can find them elsewhere.

I would like to see Trials Evolution... But exclusivity strikes again :(

pokemon. {lolz}

Journey by Thatgamecompany.

Fat Princesss!

battlefield 3 and mass effect 3 and halo combat evolved

Ico and Shadow of the Colossus

I used to play Vagrant Story on ps1. Awesome game!

MGS Series, SWAT 3 & 4..

Planescape: Torment and all the other games with infinity engine. Also some (new) german adventures from Daedalic, which for some reason aren't good enough for Valve while they still allow some real trash on Steam. I don't get it...

Unepic. i don't understand why it's isn't there

Monkey Island 3 & 4 (They got all except them)

Neogeo games from its era (We got sega classic why not neogeo especially with LAN/multiplayer support for those fighters games)
