I need a game that's going to addict the shit out of me.

I need a game that's going to grab me and keep me addicted for 40+ hours. And I need you guys to help me find a game like that, I will take recommendations for SP games for the PC and PS2. And as soon as someone recommends a game I like then I will buy it by Friday and probably post a blog or some bullshit review about it.
 
Thank you and recommend away.

Mass Effect 2.

Starcraft 2.

Stalkers Series, Fallout 3, Team Fortress.

Deus Ex

" Dragon age <3 "

Killing Floor

I really have no idea about your choice in games. Just Cause 2 maybe? Tons of crap to do with a ton of crap to do it with.

Pac-Man 
 
scratch that 
 
Ms. Pac-Man

world of warcraft

Fallout 3 and Oblivion with mods. Fallout 3 Nexus and TES Nexus are great sites to find 'em. Plus, you can buy both for $50 at Amazon.

RPG: The Game.

Dragon age
Fallout 3
Jungler
BOOM life gone

There is always Morrowind and Dwarf Fortress. Both are about as addictive as games get.

I don't know if it'll last 40+ hours, but i was quite surprised by, and really enjoyed, Plants vs. Zombies. I put a lot of time into Mount & Blade. How about The Sims 3?  My other suggestions have already been mentioned. Try shopping around on Steam.

Deadly Premonition!!!

Peggle. You can get Peggle and Peggle Nights in one giant collection for $15 and that shit'll keep you for 20 hours a piece. Then get Plants vs. Zombies and NEVER LEAVE YOUR COMPUTER AGAIN

WoW.

Elder scrolls 4: Oblivion - easily more than 40 hours 
 
Dragon Age - or tourchlight 
 
Red Alert 3

" Killing Floor "

Get your hands on a Starcraft 2 beta key. I've been playing in the past week and a half nonstop.

Left 4 Dead 1 and 2 (pc)

So far out of all the recommendations I'm leaning towards either Persona 4 or the Witcher. I've played both games but I've never gotten around to finishing them, I was really hoping somebody would recommend some gem of a game that I never played/heard of but I guess I can settle with these two games.

Super Street Fighter IV

Warcraft.

Garry's mod

Okami if you haven't played it yet. I'm not sure how easy the ps2 version would be to find though.

Vampire :masquerade bloodlines    took me about 34 hours and was quite enjoyable.

planescape torment 
 
though ur other two options are quite good
