Since I'm actually quite hyped about it... I've decided that I will very likely be doing a PbP game with at least the recruiting phase starting somewhere at the end of this year IF certain conditions are met. Those conditions are mainly having a number of players interested and dedicated, which I can see actually being something hard to obtain. The bare minimum would be 6 or 7 people (which gives me some flexibility if 2 or 3 drop). Like I said though, I actually want around 10 or even like 15 people (with half or more being very casual), including the possibility of co-DMs. The formula I put forth is as exciting to me as the simply playing the PbP itself.
In the meantime I'll figure out what ruleset to use, how to refine the PbP playstyle, how best to adapt to new players (since I want these in particular), and (if I'm lucky) how to actually run a game with more players than characters. I'm also going to slowly begin gathering "assets" and begin planning the campaign. Even though I clearly understand my chances of success are low, I'd like to go all out (I think if the thread has a lot of visual flare on my part it will keep interest and attract new blood). Alright, I won't talk about this anymore for awhile. Now where is my Sharn sourcebook...
EDIT: I was considering giving 13th Age a shot (it will be out by then right?), but I'm pretty concerned about converting material (haha, yeah, I won't be doing that by hand), particularly classes like the Artificer.
