1. Have financial woes during a economic slowdown. Mix in paying for high school, fixing vehicles, granddaughters and the Harley tax.
2. Continue running your campaign, but use what you already have or rely on free stuff.
3. Realize that you don't need to buy the latest/greatest, that this stuff works as-is, that your game still rocks.
Viola! Your ADD is cured and you can move on to a bright, shiny new world using what you have already - because there is a TON of good ideas and inspiration already there on your shelf.
(It also helps if you are still in that financial crunch and your mindset is starting to go into frugal mode.)
I think my days of just buying it because it's the latest/greatest blogoland flavor are over. I'm not shelling out anymore treasure or gold on RPG products, until I've wrung out all that I can on what I already have. I think I greatly appreciate the Depression-era thinking that my grandparents had.
Has the economy affected how you use your gaming materials? Have you become more frugal?
