I bought Halo 2 for PC about a couple days ago. Its Vista Only. I have Vista but my video card couldnt handle the gameplay so its up for sale. I paid $55 from Walmart. Only been a few days, i can look for receipt and post pic of date if necessary. But shouldnt be necessary since it was just released not too long ago. It came with an Windows LIVE card but I already made use for it sorry I cant offer that.
