Any good 2 player on same PC games?

I recently bought a second xbox controller for my laptop. The only game I use the it for is Street Fighter 4. Are there any other half decent games you can play multiplayer on the same computer?

 

Trine is half decent if you can get it on sale for $5. It has native 360 controller support and allows for simultaneous play.

And of course, old school emulator games.

Here's a list of PC games with coop (look for the "Offline" column, not all of them have split-screen coop):

Worms Reloaded. Just released today, on Steam only I believe. Great turn based hotseat game.

 

Id say this alone is one of the big draw backs to switching over to pc for me, my ps3 kicked the bucket, and although i do alot of gaming by myself or just pass controls to another person, split screen is always a nice feature to have. Co op single player can be a great experience in most cases, if you have a big enough tv (52 inch here) and a friend that doesnt slow you down.

IMO all single player campaigns should be able to co op , even if its just over the net co op , or splitscreen

 

I have L4D2 so that guide is very useful, cheers.

I downloaded N64 emulator with Mario Kart and Goldeneye. I just need another 2 controllers for 4 player!

My Xbox RROD last year and I didn't bother replacing it. I find the pc is good for gaming except for the lack of split screen multiplayer.

I would especially like to find a split screen driving game made recently.

 

Left4Dead
Worms Reloaded
Trine
Street Fighter 4

I have all 4 of those

Best mutliplayer games for me though are emulators.

MAME
ZSNES
Project 64
