well i have a little bit of money and gift cards to spend and Im not really sure what i should put my money into.

I can either get xbox live for my 360 but id have to buy the adapter which is like 100 dollars plus the sub which is like 50 each year the only games i really plan to play online would be call of duty mw2 and madden at the moment

or i could get a ps3 and have online play for free and get madden or mw2 and eventually the other, most of my friends in real life have ps3 plus i could still play with other players

i already have a xbox 360 and wii so what would you do in this situation?
