So i just sold my Wii and im getting a Xbox 360. I have about 300$ to spend. I figure i can get a system with a 20 GB for about 150$. The only way i'm gonna get MW2, is if i can get live. To get live, for one i need to buy it, and second i need a wireless adapter. Can i use any wireless adapter? Or do I have to buy an Xbox adapter? Which adapter is the best range-wise? Also, any other game suggestions? Thanks!
