Thanks for the advice so far. Sorry if this decends into intense gamer navel-gazing.
And good suggestions for charity give-aways, I kinda imagine all those soldiers on tour are out there rolling dice in a tent somewhere. It must be a bitch to get funny dice in some theaters of operation.
I don't think my "anxiety" reaches into mental health levels quite yet, although you would have to ask my wife.
It is more like a subconcious anger that I am slightly preoccupied with where I would put my game books when I have other more pressing vital issues that I should be thinking about in the back of my mind. Perhaps it is a stress response that I learned when I first started buying game-stuff as a teen.
Example:
Should I ditch this system for that? Will I never find someoneone to play 4e with in a year? I only really play basic D&D anyway. Etc.
It is almost as if I want to purge the works to eliminate my frittering attention to it.
Anyway, I have recently moved and I technically have more space for it, but I don't want to be a junk collector. I have approximately 20 tightly packed plastic banker-boxes full of books and crates of some metal miniatures and larger GW games from back in the day. (Adeptus Titanicus was awesome.) Minis are evergreen and I will hold onto them.
My experinces with getting rid some of my stuff:
sold big Car Wars collection (bought it all back later and played the hell out of it)
sold Starfleet Battles (bought it all back later and played)
sold Palladium Books (bought a couple books back and instantly wondered why I did('cause rifts is wacky))
sold original Space Hulk (goddamnit)
sold a bunch of GURPS books, bought a bunch of different GURPS book, haven't played in a long while.
sold a total Hackmaster collection because I play OSR now, no regrets
gave away Traveller reprints, no regrets because of pdfs
gave away good Pendragon collection but then played Pendragon campaign with person I gave it to (good trade)
I think the moral of the story is that for every book I ditch I replace it with something else. I am hoping that I can migrate into a PDF-reading gamer and then limit my fretting to my hard drive.
