I don't want to get involved in the whole WotC-pulling-their-PDFs debacle, but a bunch of other game companies decided to be classy and run sales of their PDF game books. That's excellent.
Anyway, White Wolf decided to give away the Exalted core rules for free. Read the details at their site. I couldn't be arsed to pay money for it*, but free is free. Definitely getting it and checking it out. Hey, it's how I got interested in Ars Magica (4:th edition was free as PDF).
*) Not their fault. Just the whole "I already own a heroic fantasy game" thing.
