The Game Engine came about when I realised that a particular game I had just purchased was seriously lacking in some playability. The players I was talking this over with agreed and I thought it'd be great to have a generic site that could host house rules for game systems. So, this domain was available and I grabbed it.
I'll make more info available as I add things to the system.
If you would be interested in a subdomain to host your site on please feel free to contact me. Tell me a little about the game and the requested sub-domain you'd like. I can provide you with a decent number of facilities to assist you in developing your house rules. Forums, a facility to build "pages" of the site into a book like structure, etc.
