'As someone who often uses Board Game Geek (BGG) for asking (and answering) game related questions, I'm very much drawn to the SE format. SE creates an excellent architecture for asking and answering questions, and for keeping both the questions and the answers on track, focused, useful, accurate, and easy to find. BGG, though it has many other unique benefits (notably its huge database of game images and general game data) is a very inefficient and frustrating place to seek (or answer) questions: the signal-to-noise ratio is extremely low there, and there is an enormous about of false or inaccurate information, and finding things is a chore.
This site, however, lacks the critical mass of content it needs to reach its potential as the primary place for game related questions. One approach to remedying this is of course is to try to directly recruit users, but it's hard to imagine that users will show up without the content to draw them here.
Can we copy (suitably edited) questions from BGG, along with the best, accurate answers (as CW, if that's the right approach) as a way of populating the site? Can users undertake this as a large scale, explicit project, of dozens or even hundreds of questions? I'd much rather use SE as a reference for rules questions, than BGG, and I'd much rather "store" existing, already answered questions on BGG here.
I should add, that the goal is not to draw away from BGG, but to get BGG users to contribute questions and answers here so that they can take advantage of this site's better quality control and organization. Done right, this should actually increase BGG traffic, as the posts here should have links back to BGG, especially where they paraphrase, summarize, or expand on posts there.
