I have room for 11 games all up, and have gained space for two recently, so 9 are playable ATM. I don't have any stored as such, but have a Joker Poker at a mate's place, and Flipper Football at my mother's place (and yes, she plays it often).

I decided that I would keep my collection to only the area I have space for, otherwise, being a hoarder by nature, I would definately need storage space!!
