Greetings from Shanghai. I'm a 'Basic' D&D player too, currently working in Shanghai. I surfed into this site, so cool.
I have written a campaign world specifically for Basic/Red Box rules that we use here. It's kind of like The World of Greyhawk boxed set, except with way more space in it for sandbox / customization. I would love for some players outside of our group to have a look at it. There's a Jpeg of the map and a small PDF guide book.
Message me through the forum or ask questions here, I'll be happy to e-mail it to anyone. It's all free and all open for use / non-profit pillaging.
If no one is into it, that's cool too, keep up the good fight for old school play and sensible "coolness".
