I've written the basic mechanics for a new role-playing game, and I wanted to crowd-source the details, like writing specific spells, creatures, items, etc. Do you think SE would be a good place for something like this: i.e., an official SE RPG?
The system uses opposed rolls, where you roll your boxing skill to hit me and I roll my dodging ability to avoid the hit, and I was calling the difference between the totals the "overroll", so I thought Stack Overroll might be a good fit. However, I'm not sure if the SE question/answer format is robust enough. It would also need some way to say "Yes, this has enough up-votes and is now canon". It would also need moderators with some ability to tamp down on power creep. I would love it to have a self-imposed movie-like rating system so kids could filter for G or PG ratings. And, of course, if younger people are interested there would need to be a nigh-draconian anti-troll/sexist/jerk policy. There might also need to be a way to occasionally print the currently-cannon rules and sell them at a bookstore.
I believe there's a great business case for SE: people would be on the site for several hours during a game, looking up spells or monsters. I also believe the good folks on SE would love a creative-but-rule-driven outlet.
Edit: The goal is not to turn SE into a game engine, but to use it to write a tabletop, pen & paper game system. And not necessarily within SE:RPG, but a new area, tweaked for this creation format, as opposed to just Q&A. The linked question below is...horrifying. There would be a page with the basic rules, and the community can add additional content, with community input. SE:Overroll would be an online resource to look up "canon" spells, creatures, etc., while you're playing the game at home around a table with your friends. A crowd-sourced, free, pen & paper & laptop role-playing game.
I started with AD&D in my college days, and when I look at it now I'm very concerned that it has become too complicated for young players to pick up. I want a system with easy basic rules, but that is highly extensible. I came up with a system of mini-classes, like Pyromancy and Swordsmanship, and you start with two, adding more occasionally as you gain levels. Each mini-class ("skillset") is easy to run, and you only add more after you've become comfortable with the existing ones. You gain 1XP whenever you use that skillset, and 2XP if you fail the roll. Clean & simple, with minimal in-game record-keeping.
