Been playing my mash-up of 1e/2e for years... I was hiding under a rock for many years and didn't even know about 3.x till about 3-4 months before they were announced 4e was coming out. My group still plays my 2e game now and again, Pathfinder, and 3.x games. I am much more freeform, and we mix things together and use what works for us, and toss what doesn't.
Just out of curiosity, where do is the Paizo warehouse itself located? I ask because I'm just 20 minutes north of Renton in scenic Lake Hills, and I ordered a few books over two weeks ago now with no sign of them. I'm thinking if your warehouse is also here in Washington, I should get in touch with the post office.
Obvious question but did you already get an email that the order has shipped?
