well, it wasn't just RPG money that has improved things, my finances have gotten a little better, by about $400/month, so I have been buying new clothes and tools and numerous other things I have been putting off in the past due to tight finances. I'll be spending like this for another month or two, then I'll tighten down again and use the extra cash to pay down credit cards, etc...
Heck, I actually have been spending more money on RPG's the last few months than I have been for the last 2 years. Not much on 4E though. Other RPG's, like the Twilight 2013 pre order, I bought someones collection of their Dragonlance D20 stuff, bought a bunch of Goodman DCC PDF's on December 31st, renewed my subscription to Pathfinder which I canceled 10 months ago, and just yesterday I ordered two new C&C modules and renewed my annual subscription to Crusader magazine.
I am considering getting some more Warhammer books and some more Aces and Eights stuff before I tighten my belt back up. Plus I am considering getting Fiery Dragons new counter pack bundle, even though I don't play 4E anymore.
