So post here what you'd like to run, are running, or ideas you have thought about running. I like to hear others ideas. Here's a whole slew of what I've been thinking about.
D&D Eberron: You've all heard this, I'm basically running the published modules (except Whispers...uh!) and then branching out on my own.
D&D Adventures: Basically a low time commitment D&D game, probably my back up if Eberron falls through. The PCs will acquire a keep early on which will serve two purposes: a home-base for the campaign and a money-sink which they can upgrade (a good reason to adventure). The campaign would have no meta-plot other than that. It would just be running modules or homebrew adventures...kind of like Jeff did with Hackmaster. Anyone could jump in or out at any time without worry. Plus, it could be run Troupe style so someone didn't have to DM the whole time. Pretty much the way D&D was played back in the day, but with 3.5E.
Savage Worlds Necessary Evil: Mmmmmmm... supervillains. The plot for the game rocks on toast. Would certainly be fun to play.
Savage Worlds Tour of Darkness: Thinking of running this to pull some of my non-gaming friends into the hobby. Their love of historical strategy wargames could make this a viable option. Actually, Weird Wars 2 would be better, but it's not out yet of course.
Angel - The Dark: People seemed to like my Buffy campaign. I know it was just about the most fun I've have running a game. Everyone really got into their characters and tried to emulate the show in all the good ways. My departure to Kansas City cut it short, but at least it actually ended (unlike so many other of my campaigns). The game was set in 1999, and ended just before the new year began. While I love the Buffy RPG, the Angel RPG is better for running any game not set in high-school/college/etc and as an added bonus if just about completely interchangeable with the Buffy RPG.
The Dark would revisit my Buffyverse version of St. Louis in present day. There's a lot of mystery and weirdness still left to uncover next to the bloody 'ol Muddy. This time, the cast are adults and the themes are more mature - leaving the fun-turned-deadly high school hijinks behind as Angel the Series did. The cast will be all new with the option of reprising their roles from the original series. Of course we have to figure out how they escaped from being stranded in the demon dimension the Lemps called home, but that's what flashbacks are for
Savage Worlds - Deadlands: Yup, Deadlands still rules in my book. I'm not entirely happy with the stop-gap free Deadlands to SW conversion rules currently available, but they're better than nothing. I would still love to run a Deadlands game. I may do it as a one-shot sometime or other. I think I'll wait for the full book to come out before comitting to a full campaign. C'mon Shane, write faster!
Buffy - The Gateway Season 2: I could run Buffy again, starting where the last game left off (on a very un-Josslike cliffhanger), but I'd rather run Angel.
Savage Worlds - Necronauts: Inspired by the premise of Orpheus and Flatliners, this would be a pulp era game about exploring the world beyond death and then blowing it to smithereens. Not too much developed here yet, just the basic idea.
Savage Worlds - Ruins Redux: Ruins didn't go anywhere near how I thought it would and I'm not that happy at all with how it turned out. The players did a great job, but I fell through as a gamemaster. Given the chance, I'd like to run a game starting with the same premise, but do it right this time. It would be run concurrently with Ruins history, but be set in a different part of the world. This is more of a pipe dream, there's a lot of stuff I'd rather run before this.
