You could've just bought a 10 or 15 dollar gamepad...

Actually, it really wouldn't. A dual-core can run CC just fine; the 360 has a tri-core processor, plus it also has the advantage of having a really lightweight operating system.

It's three cores that are less than a third of the ability of a PC's core now.
It's like 800MHz per core or some number like that.
Not enough to run CC without lag.

I just checked, and each core is 3.2ghz.

I tried an xbox controller, it was pretty neat, takes getting use to.

Same, I have trouble with this new-fangled mice business, and besides, it's way too hard to play 2 player on 1 keyboard when player 1 has to spoon player 2 if they want to do anything.

I'm using classic keyboard arrow/numpad controls.
I've tried to play whith my gamepad (logitech) and it is way over sensitive.

Speaking of controllers. when i play keyboard+mouse vs gamepad unfortunate things happen. when i(keyboard player) attempt to sharp aim, if my friend (gampad) moves my sharpaim is lost. any ideas because it gives him quite the unfair advantage.

Howdo you get the 360 controller to work for the computer, again? I connected it with my USB charger, it asks "Do you want to install this app" or something of the like, I choose yes, and it says it can't. And when I turn on the controller it turns on my Xbox and won't for for the PC. It would own to play CC against my brother though.

Dualshocks work pretty good I must say, and with one of those 4 port USB adapters, you've got an instant party. Maybe CC will include rumble support sometime.
