My favorite game to play online is UFC Undisputed 3 because it seems like your a real life UFC fighter. I love trying to knock out my opponenet or submt them whenever the fight hits the ground. You can also use your created fighter and dominate the competition.
I prefer wire controllers because I can't tell you how many time my wireless controller died while I was in a ranked match online. Made me so mad and I threw the controller at the door.
