Why don't you just go here and type the name of the game in, and see if it has an online icon?
What is the point of having all three systems when I am going to be stuck playing one of them the whole time? I am getting a PS3 the day that Uncharted: Drakes Fortune comes out, the Xbox 360 just has too many flaws for so much money, and the Wii, I will NEVER get it. Oh, and if this has compared the systems, which I don't think it has, please remove it.
If I ever leave a smiley face as a post message, it is a link.
