I've considered doing this too. Mainly because I'm trying to become more financially responsible and if I sold off all my pins, I would be debt free (plus some cash) except for my mortgage. I actually don't play my games as much as I should. I think my true enjoyment of the hobby is having friends and family come over and play them, which I guess is ok...
I'm trying to get rid of stuff in general too. Stuff I don't need. But I know where you're coming from. The old saying on how possessions begin to own you is quite true...
