I'm an bit of a retro gamer at times, so I still have my old consoles as well as adding to the pack every so often. Right nowm I've only got my 360 hooked up, but I also have a Wii, GC, PS2, Xbox, PS1, N64, Saturn, Megadrive, SNES, Master System, DS, GBA, SEGA Nomad and an Atari 2600 which all see varying amounts of use depending on what mood I'm in. Well except for the 2600 because the power cord is broken and I need to get a new one.
*EDIT* Can't believe I forgot the Dreamcast. Its only one of my favourite consoles of all time.
