I'm hopefully getting Phantasy Star Portable 2 later today.
Yeah I never got into CIB NES collecting but I figure it's like everything else. Except for...you know...more expensive on the high end. Though anime does have a really dumb high end. I'm not sure where CIB NES collecting maxes out (stadium events aside). I know it's not as bad as sealed and that some games you can't even get CIB (promo carts etc).
