I've been a PC gamer for ~3 years and never even looked back to consoles since I built my PC. However, now I have a group of really really good friends with whom I eat lunch most of the time and I also party with them. They play on XBox 360 almost every day. Right now I can buy a 120GB used Xbox for $80, I would just need the games they play and a way to connect it to my PC speakers. I know I would get a lot of fun hours in multiplayer with them. But I'm not sure it is a good investment. What would you do?
