Hmmm... so I seem to have 5 prospective players already. I guess that counts as sufficient interest then! I even managed to attract some regulars (Ferrix and Isida, I feel like I need to suck up to you guys somehow... do you want me to fudge some starting scores for you or something?

).
All those ideas look sweet so far. Although I'm not a big fan of Action Points, so we'll have to work something out as regards a modification of the Extreme Explorer (and change the name....ick). I can just about put up with them inside Eberron itself, but I'd rather keep them off the planes as a whole.

I guess I'd better get down to some serious plotting and scheming then. Planescape just isn't Planescape without some real rat-bastardly nefariousnessness. Ness.
So... let's have some input then guys. What do you like best about Planescape? Least? Do you want some Sigilian politics? Or would you prefer planar exploration? Pre/post faction war? What kind of power level are you interested in playing? I'm quite happy to DM for anything from 1st level through to Epic levels (though in that case I'd be working purely from the SRD). If you want to tie your characters together in their backgrounds, cool. If you want me to worry about all that instead, that's cool too. Do you want a character development-intensive experience with lots of DM-player collaboration and plotting and piling on the personal drama? Or just a good laugh (with Mephits!)?
Really, the ball's in your court to tell me what drew you to want to play in a Planescape game and what you want me to focus on. Then I'll try to take all your requests and furnish them into something cohesive and cool. This isn't an attempt to avoid responsibility, but rather to ensure we end up with the kind of game you guys all want to play. While I'm here, in the style of all those irritating RP books that give you 'sources of inspiration' anyone who hasn't already should really check out
Shemeska's Story Hour, one of the finest Story Hours around and my prime candidate for number one thing to make you think 'wow, I really do wish I was playing Planescape right now'. Other useful sources for all things Planar are, again for anyone who doesn't already know of them,
planewalker and
the mimir. The races from planewalker.com should be fine, but if you're going to want to use any of them then run it by me first, okay?
