Morrowind.

It's such an alien place, I had to experience it all. I was never really a completionist before, but Morrowind showed me that yes, games could be as immersive as books and just as capable of creating a world that was both believable and unmistakably different.

Probably Dawn of War 2 and its expansions. The fact that the campaign isn't too long and there's a loot system really helps with the replayability.

I'm surprised to see this. I bought 1, 2, and the expansion to 2 in one big box back in the day. Played a bit of 1 and enjoyed it, but it never really hooked me. Warcraft 2 though, that I loved and played a ton of. I even replayed it a year or so ago and it holds up wonderfully.

The original Thief, hands down. I can beat the vanilla version in around 45 minutes and the Gold version in less than 90 minutes

A bunch of the Call of Duty campaingns for sure, especially 1 and 2

Red Dead Redemption

Resident Evil 2 of course

Bonkers on the SNES (Yeah I know okay)

Knights of the motherfuckin Old Republic. I lost count of how many times I played through this damn game.

Condemned: Criminal Origins. Like bumfights just went out of control.

Assasins Creed 2. Just to give Leonardo Da Vinci a hug ^_^

Edit: I almost forgot Half Life. I played it religiously for a few years. This was even before modding really took off so I played it through vanilla style every time.

I can beat the remake even faster. I just turn it on then turn it off.

You must have one hell of a memory then! The first Thief's levels can be incredibly convoluted, like that damn sewer hideout level :P

That level in particular is indeed convoluted. BUT... a lot of that is just filler. Once you know your way around, the level can be beaten with ease.

Fun fact: Thief 2's final level usually takes me longer to finish than Thief 1 in its entirety. :P
