So you've listened to the D&D podcasts I did with Scott Kurtz, Gabe, and Tycho…
You've read my series of posts about playing 4E with my son and his friends…
You've read my post about being a Dungeon Master…
You've read my other posts about gaming, especially how much I love D&D, how surprised I was to actually like 4E, and the backstory for my Avenger…
You have an appetite for gaming, and the only thing standing between you and actually giving 4E a try is the not-insignificant investment in core books and stuff….
Well you're going to dig this news quite a bit, I think: Wizards of the Coast is making D&D 4E's quickstart rules and its first adventure, The Keep on the Shadowfell, available as a completely free download. They've also thrown in the free version of their 4E Character Builder, because that's just how they roll (up new characters, yo.)
Still not interested in 4E? No problem. This is also a good time to point out that my friends at Green Ronin have had the True20 Quickstart Rules and Death in Freeport online as free downloads for a million years, and my friends at Steve Jackson Games do the same thing with GURPS Lite.
Now go forth, my friends, and hurl many polyhedrons.
