I collect for some things if I'm going for like a franchise, such as I have a Sonic game for the Game Gear, or I don't have a Famicom or Japanese N64, so I can't play the Japanese Zeldas I have. I am considering collecting for something like Saturn/Sega CD cause I love their cases if I can find them in the wild though. Don't have the systems, but they look pretty nice for display and one day I'll probably get them.
