3/5 of my games would be very tough to sell for various reasons.

MMR LE- Was a gift from my ex wife (we are still actually good friends). I played MM quite a bit in college but never really thought about owning one until 10 or 12 years later. By that time the prices were 7k and rising, which I thought was too much. Once they hit 10-12k I wrote the game off as a grail and something that I never really would break down and purchase. Super long story, she purchased one for me Xmas 3 years before it was actually delivered (everyone here knows the pre order drama with PPS) After 3 years of waiting, and a decade of lusting, I would have a really hard time letting that one go...even though it does get the least amount of play in the collection at the moment.

MET Pre- Perfect theme, integration, art, and gameplay for me. Unlikely I would sell unless I could get a roadcase or MOPLE without too much of a cash outlay

IMDN Pre- Simply one of the best games I have played, bought NIB and can't imagine selling

AIQ Pre- Great game and art, the rules confuse me and the callouts and animations are MEH. It could be sold, but it would need to be a great theme and playing game.

TMNT Pre- Surprisingly fun game. The kids absolute favorite so it gets the most play by ALOT in the lineup. They don't want me to sell, so if I did it would likely need to be approved by the little ones.

Really wish I had more room! 5 fit comfortably in the game room...not sure If I want to start invading other rooms just yet, or ever.
