Best PC games ever played?

Mafia: The City of Lost Heaven

Too many to name and i have no time for that right now.

Metal Gear Solid best interactive movie I ever played....

Bioshock 1 & 2, still not played Infinite because bought the Season Pass and now it likes to download another 21.7Gb lol, Portal 2, Tomb Raider, Deus Ex Human Revolution, Half-Life 2, Dishonored, The Walking Dead Season 1 & 2, and probably some of the Assassin's Creed games, and maybe I remember and add more after. Adding: Black Mesa, Bastion.

Half-Life 1 and 2. I'm playing now BioShock and it's really awesome, I think it will be the best game I've played. You should try it, I'm so surprised.

Don't Starve, FTL, Portal, Guilty Gear

For me it was definetly World of Warcraft (until Cataclysm).

Dark Souls Prepare to Die Edition and L.A. Noire are some of the best games I've ever played.

Battlefield 2 PR Mod. So many intense or funny experiences that never got recorded.

StarCraft :)

You can pick between Doom 2 and Thief 2.

Bioshock Infinite and Spec Ops: The Line really left a mark on me with their story, but the game I most enjoyed playing was Sleeping Dogs. After playing that, every other open world game (especially GTA) just feels a lot different. I'm hoping GTA 5 would change that, though :D

Starcraft ,Bioshock infinite ,C&C series and Half-Life series ofc :)

Borderlands, the first one was epic, and the Borderlands 2 is AWESOME, the best example of how to improve sequels

The 仙剑奇侠传 and 轩辕剑 series.

motocross madness old but never matched

Skyrim , Walking Dead Seasons 1 & 2, Batman Arkham Asylum ( my computer isn´t good enough to run the others), Mass Effect and Fallout 3 are my favorites.
If you're looking for a game to play with your friends I'd recommend Left 4 Dead 2

really enjoyed jagged alliance 2 back in the days :)

Just Cause 2.
Brings back memories even though it hasn't been that long...

I want to say Dark Souls PTD but with the shitiest port I've ever seen, and they aren't even try to fix anything, I can't.

so...uh, probably Bioshock 1

Killing Floor, CS:GO, Telltale's The Walking Dead, Stubbs The Zombie, UT 2004.

Super mario...?!

Dragon Age Origins !!!!

E.T. on my Atari 400

jk... although I did play it back then.
Played many great games over the years... none really perfect, especially in retrospective, but at least some that came close.
I've I'd have to pick an older game, I'd probably say first and second version of The Settlers, although other classic series like C&C, WarCraft or Half-Life are a given, too.
