i've played it. mouse worked perfectly (hate the game tho. never played much of it)

but i play FPS online for PC all the time.

Quake 3, now UT2003 battlefield 1942.
the mouse is best for FPS online

i mean, once you use an optical mouse, you'll seriously wonder how you ever did without, you can aim quicker and more accuratly, if your sniping, and you want to move it just a hair, you can do it.

i remember when i used a ball mouse and i was sniping one on game, i tried to move a hair. and the damn ball would get stuck, and have to move it a bit more, then it would go too far.
*mumbles*

you'd never want to have a ball mouse again, i dred going to someones house and they have a ball mouse. i yell at em. hehe.
