I'm a game-a-holic. I'm notorious for getting really interested in a game and then immediately getting interested in something else. A lot of times I'm looking for a new game but just don't know what I want...so I sample a lot (much to my wallet's grief). I was in and out of Magic within two weeks, I'm still not sure about Warcraft though.
I actually don't spend that much on gaming though. I usually sell off some stuff I don't use and buy new stuff. So I spend very little net money.
Right now, I'm not collecting/playing anything. My Warmachine stuff is just sitting here and I'll probably sell it soon. The only gaming interest on the agenda is roleplaying.
So I'm going to start a new minis game, Star Wars. To replace Warmachine. I also slowly buy D&D minis. I can use them for RPG or use Savage Worlds for mini game fun.
All that said, there are a few things I stick with... Deadlands, Savage Worlds, Buffy/Angel, and some form of mini gaming.
