OD&D, 1e, 2e, 4e, Next, Terrestrial Interest Probe.

I have an idea. But after my second no-show, a more cautious approach seems to be warranted. The Idea: An episodic D&D campaign set in space, with rotating DM's, and a Kirk-ian disregard for established rules when they get in the way. Though not exactly space-travel in the Spelljammer way. More captain Picard, and less captain hook, if you take my meaning. Every player (or almost every player) would also take a turn DMing at regular intervals, or for a term determined by consensus. Rules system has some flexibility. I know 4e, OD&D, and some Next. But I want to learn 1e and 2e. Physics would need to be determined as a group, or ignored entirely. Or both, depending upon the will of the DM. Basically, I'd like to improve Star Trek the only way it possibly could be. By adding swords! Also, Star Wars, Firefly, Hitchhiker's Guide to the Galaxy, and Battlestar Galactica. Because I'd only mentioned Trek so far.

D&D Next-raterrestrail gaming? :) Your subject line may appeal more to the Earthly players of fantasy RPG's, as you've mentioned terrestrial and OD&D. You know there are other RPG systems that go into space, even some that have a space-with-swords flavor? There are old-school space RPG's, and there are contemporary refined ones too. You could check out some other systems since you seem highly flexible about the system anyway. Your idea sounds interesting. As for me I am not looking for mixing in as much spaceplay, and I like playing towards the earlier end of the D&D system spectrum myself. Good luck, force b with u.

Nah, I'm not too interested in changing systems . Especially the ones you might call "refined", as they've already anticipated everywhere I'd want to go. The terrain over the next hill will be somewhat less mysterious and inviting if you already have a detailed map. No, the space itself would initially be little more than a plausible way to change the setting and features of the world. I have lots of ideas that burn holes in my head trying to make it to the outside world, and space seems like the perfect way to use them all!
