My 2c
An enthusiast - someone who plays often and may or may not have a few pins at home. If they have a game, probably would be kept in great condition.
A collector, someone who buys for a reason and has several ie more than say 3 pins, all chosen for specific reasons other than just being pinnies. Ie AFM, CFTBL, STNG, TRON, BoP, so they're all Sci fi (ish), in my book they're collecting Sci Fi themed pinnies. This person would spend money on upkeep.
Hoarder, someone who has many pins with no common theme and by definition does not do a top job maintaining them (like a collector would). Hoarding tends to be a bit aimless and fetishlike... ! Hoarders might also be deemed to be a collector of Pinnies in general, but a hoarder would not in my book invest much money and effort in their upkeep. Thye just have them because they want them.
All hoarders should be shot on sight and their games returned to the market.
