Having always been a XBox or Nintendo owner I'm torn on whether I should buy a XBox 360 or a Wii. I hear how fun the Wii's are all the time, but I must have Halo 3. Should I wait until Halo comes out on PC and just buy the Wii or does the XBox have the much over the Wii. Also, having never played any games like Halo 3 on my PC. Is it the same as playing it on a XBox? Or is it a definate downgrade? I'm running Windows XP with nothing special added like gaming video cards.
