So, time for some real nerd shit. Over the past few years, my bros and I have been developing a system of pen & paper role-playing rules. We think it's pretty good and recently we wrote up a doc with the core rules in it. I think y'all might like it because it's got some interesting game design ideas and takes a critical approach to rpg design. You can use it to run a bunch of different sorts of games. We've done surreal alternate world war 1, traditional fantasy, modern-day horror, and not-steampunk (I forgot the steam). Other playtesting groups have done noir and lovecraft style horror. I'm pretty sure you could do attack of the killer jpeg compression time portal convincingly if you wanted. We provide a pack of starter settings called Kindling if you don't want to come up with your own premise.
Our site is
http://www.locusrpg.com and you can get the rules from there for free. They're designed to be extended and are creative commons. It's beta at the moment because we're testing the text. The game as we play it certainly works. I could go into the theory of it but I'd rather that people give it a read and try it out. Hopefully it's quite accessible. It's very short. Not everyone likes a 300 page rulebook with the ridiculous dragon pictures. I did some quick drawings to brighten it up a bit and we also have a logo. It's been through a lot of rounds of edits and I'm sure that online release will result in more.
So, yeah. A lot of people here have really good opinions about game design and I'd be interested to see what SaltW has to say about it.
