@killerchameleon: I agree with you. I've got a Socrates but I wouldn't consider that a game system. Yes, it could take different carts and yes, it plays games, but I guess I consider it a toy. Then I have a TI-99/4a but to me, that's a computer.
Maybe toys and computers should be able to be documented on here as well, since they do have games, but I'll have to be pretty bored before I start doing inventory on all that. I need to finish my "real games" first. (I looked the other day, I've added 15 gameboys to my collection since I've updated on here.)
