My collection in LB is 400-ish games, and I have games from a myriad of obscure and some slightly newer systems.
I'm talking Tiger Game.com, 3DS, Wii, Xbox, Watara SuperVision, VTech CreatiVision, Emerson Arcadia 2001, and more.
Edit: I obviously have games on the more well known systems like NES, Genesis, PS1 and stuff like that.
