i would say all of the above....some are bought to fix, clean, play for a bit, and sell to help bring on that new game. Completing my second full top to bottom restoration and hope to do at least 1 more this winter. My keepers (AFM, MM & SM for far) are hopefully going to stay for a long time which would be the collector part. Tough question...I guess I go into the hobby to be a Player but decided I wanted all the best games and the only way I figured I could do it was by trading/selling and making my way up. My head hurts, I dont know which answer to choose?
