My sons birthday is coming up this weekend, and he's a Pokemon fanatic. I was thinking about picking up Pokemon Stadium 2 for the N64 and Pokemon Crystal for his Game Boy Color. The thing is, Stadium 2 is still $60!!! I was thinking about stopping by Gamestop and picking it up used for $40, but doesn't it use a battery to save information? Is it a good idea getting this game used instead of new? Granted, he'll be getting a Gamecube of his own from his granparents in about two months, and I'm sure Nintendo's cooking up a new Pokemon to use with it, so he won't be playing it long. I'm worried about that battery, though. In both Stadium 2 and Crystal. What do you guys think? Freddy C.
