I love the OGL, man. It continually gives us an ever-growing smorgasbord of D&D variants, such as Warriors of the Red Planet! This is, of course, a sword & planet variant of the rules! Awesome, another bit of useful house rules that I won't have to create myself ;-)
This is the softcover beta of the rules you can get from Lulu right now on the cheap. The game's creator - Thomas Denmark of the WotRP, Original Edition Fantasy, and Studio Denmark blogs (and creator of the Dungeoneer game) - has been working on this for a while, and to be honest I had all but given up on this game seeing the light of day (not because of any failing on Mr. Denmark's part, but just because the development was taking so long).
But I'm glad I was wrong! I have had some time to read through, and it's pretty cool so far. I hope to have a full review someday, as soon as I can get to it.
This thing has me so excited about planetary romance that I had to break out my copy of the gorgeous John Carter of Mars collection illustrated by Thomas Yeates. Hmm, might be time for a re-read!
Anyway, I would love to find some time soon to help playtest these beta rules. Yeah, seriously, this has me so excited (as does the Dungeonteller game, which also just hit the streets) that I might need to come out of my current roleplaying hiatus! Stay tuned...
