I've recently been expanding my Gamecube library; it's probably the 'retro' console I now spend most time on, and along with the Dreamcast probably my favourite catalogue of games ever.
I only wish I could find Killer 7, Tales of Symphonia and MGS: Twin Snakes... then my library would be complete (I have the Metroid Trilogy on Wii now).
