This is excellent! I’m pretty much just a 4th Edition player, and I plan to pre-order a set of these as soon as they’re available from my FLGS. I’d love to have my own copy of the original Dungeon Master’s Guide in particular, but also the Player’s Handbook and Monster Manual. And it benefits the Gary Gygax Memorial Fund. Too cool!
I’m very encouraged by this. Maybe WotC will have some success in uniting the D&D community after all. Way to go WotC! April 17 can’t come soon enough.
