When I made this site, one of the things I'd originally intended to use it for was as a repository for all the little snippets of ideas I had. Things that I didn't necessarily feel warranted an extensive look into, but that I still felt had some merit as experiments.
On that note, I've put up Balance the first of several "micro-RPGs" I've been intending to release. It's not an extensive or all inclusive system, but it is a neat little experiment, with a unique resolution mechanic that I feel is worth a look.
Plus, it's free, so there's that.
