Which steam game do you like the most?

Steambot Chronicles has always been my favorite.

Old and awesome: Lugaru HD, X-Com.
New: Killing Floor, Garry's mod, HiB3, Terraria, Counter-strike: Source and lots of other games.

Dark Messiah of Might and Magic. If only the game was more open world and less linear, though the combat mechanics are fun as hell.

The game I have the most hours on is Garry's Mod.

portal

Uru: Complete Chronicles, for strange reason a forgotten and overlooked game, much like the rest of the Myst series. However, there is a free online version, I just don't have anyone to play the cooperative ages with D:

Whole dawn of war serial,Dark messiah SP and soon Space Marine (demo was awesome I bet the whole thing will be aswell)

monday night combat

Team Fortress 2 and Killing Floor

Tropico 4

Bad company 2

Bad Company 2

I see there's not as mutch people as before, who likes Tf2.

Bad Company 2, DIRT 3, Red Orchestra 1 (Wainting new one, will be awesome :D )

Renegade Ops

Fallout 2.

Farm Simulator 2011, Virtual Families, and Rig & Roll.

It changes a lot for me. lately I've been enjoying New Vegas a lot, before that it was the AC series. But overall game that I return to a lot would be Mount & Blade: Warband.

team fortress 2 lol i got 600 hours of fun in it

TF2, Terraria and Titan Quest: IT :P

Team Fortress 2, Counter Strike 1.6 and Source

Sims 3 since it's the only Steam game I can run. Too bad nobody gifts expansion packs here.

Eufloria :з

All 3 Deus Ex games and TF2. And yes, that 3 is not supposed to be a 2, I did enjoy Invisible War (just not as much as the other 2).
