Good luck with the home hunting, I'm kind of on the fence with the same thoughts. Thinking about slowing down a bit after I complete this original Xbox collection(166 to go) as I'm at the point now where part of my own house hunting is to find a bigger place for all the games. lol It'd be nice if the dog had a back yard too, but it's mostly no room for games.
I've been getting rather tempted myself to sell off some high priced Turbo Duo games... They just sit on the shelf, people are willing to pay ridiculous prices and I never bought the system to play them on anyway LMAO
Count me as one of those interested in buying a TGCD game or two if you sell. I've got a TGCD and no games to test it with, tested a music cd to make sure it at least read discs when I bought it 6 or so years ago, but I've never run across a TGCD game in the wild since.
