So! We're thinking of starting up a roleplaying game at our house, and hope that you'll be able to join. If you're interested, here's the current plan, and some ideas I've had for a campaign:

Place: our house, 10855 31st SW.
Time: We're thinking Sunday afternoons, maybe 1-ish?
Frequency: Maybe twice a month?

Game systems: Here's where we need your input on what you're most interested in/comfortable with. If any of these sound more appealing than the others, or less appealing than the others, let me know:

Systems I have books for:

D&D 3.5. There's also a wealth of information online for this (d20srd.org), so getting the rules shouldn't be a problem. It's a solid, classic system, and I'm at least roughly familiar with it. Lots of crunch, if you like that sort of thing (and I'm generally OK with it, myself). My one problem with D&D in general is that you can spend a lot of time swinging and missing, which isn't all that fun, but I might be able to tweak the bad guys to mitigate this and still have it be challenging.
7th Sea. I have a *lot* of the books for this, and I've played it extensively online, so it would be pretty easy for me to GM, and there's plenty of extra bits you could find from the books I have. It has its flaws, but this is the one I know best how to tweak to make it more fun for me (and I know how to head off problems in character creation that would otherwise lead to power imbalances)
The basics: swashbuckling in alterna-Europe in the late 1600's, with the 'good bits' of European history from vaguely that era thrown in, plus some magic. The system itself isn't quite as swashbuckly as its creators would have liked it to be, but it can be appropriated for the task.

Spirit of the Century. (aka SotC) Sara got me the book for Christmas last year, and I've played it a bit online and like it. It's a much, much, simpler system than the other two, and generally does a good job of playing to that simplicity's strengths. Designed for 1920's-style pulp action-adventure stories (think Indiana Jones; The Phantom; Sky Captain and the World of Tomorrow; that sort of thing). Character creation consists of choosing how good you are at different Skills from a list (you get one great, a couple good, three decent, etc.), choosing a few Stunts from a list (which generally are associated with one of the Skills) (I'm OK with making up a new Stunt or two here, too), and then making up anything you want to be Aspects which give you bonuses and might get you in trouble, too (stuff like 'Scrappy fighter', 'Mad scientist', 'It takes a thief...', or even 'Intelligent ape!')

Other options:

A SotC/7th Sea mashup. Basically, SotC rules with 7th Sea flavor. My friend Dan (who's joining us) has been mucking about with ideas for this; if we wanted to use 7th Sea for its setting but with a more rules-light system, this could be a good thing to try: http://inky.org/rpg/design/sotc-7th.html
(An additional potential wrinkle: starting off lower-powered, so we can do some advancement, a la http://evilhat.wikidot.com/advancement3
D&D 4.0 I don't have the books, so we'd have to obtain them, but the system does look interesting.
A superhero game. I've heard "Truth and Justice" bandied about as a good option for this, which would be inexpensive, and I'm at least somewhat familiar with the underlying PDQ system (Prose Descriptive Qualities): http://www.atomicsockmonkey.com/products/tj.asp
Something else? I'm open to suggestions, and we don't have to stick with the same thing forever.

Setting: This relies somewhat on the system we pick, but there could be some crossover. If we go the D&D route, Sara and I could dust off the old world we created for a campaign I ran for a while in early grad school, we could try the Eberron setting (which I've heard good things about, and which Dan might have a book or two for?), or we could just go with 'generic fantasy land' and fill in the gaps as we went along, starting with character creation.

One option for a purely adventuring group would be to do a 'West Marches' style game (http://arsludi.lamemage.com/index.php/78/grand-experiments-west-marches/) where the world is set in stone and the players venture out into it, questing for fame and glory.

If we went with 7th Sea, one idea I'd like to try at some point (but which not might be the best idea for starting off?) is to have a 'Los Vagos' campaign, the 7th Sea version of a Zorro secret society. I'm particularly interested in trying a game tied to a place very familiar to the characters, where the adventures come to meet the players, instead of the other way 'round. If ST:TNG is the traditional adventuring party, this would be the equivalent of DS9 or B5. Los Vagos is tied to the Spain-equivalent country in 7th Sea (Castille), and is generally dedicated to fighting the injustices of the inquisition and protecting Castille's boy king from plots and politicking. If we went with this, I'd want to start with both character creation and town creation, and figure out a lot of connections between the players and each other, and other prominent NPCs in the town.

Another 7th Sea idea would be to leave the continent entirely and send you off on a mission to discover/explore the America-equivalent (officially undiscovered in the books).

If we did SotC in the default setting, I'd probably get adventure ideas for you all as a by-product of character creation. It has a pretty good method for group character creation where you all make up previous adventures you've been on with each other, and a lot of grist for the mill gets generated. I'm open to SotC in other settings as well--we did one online game with SotC in a Conan-esque world, which worked out pretty well.

Campaign style: I'm inclined to go with something short-ish at first with a natural conclusion that we could then do a sequel to if we were all still having fun with it. And then when the probably-longer sequel is done, we could then again either do another sequel or switch to something new.
