New Project

So, in addition to planning for my new campaign, I'm working on a new Old West-themed RPG, which will be pretty rules-light and similar to an OSR game as far as character creation ( rolling up characters,  character classes) I'll probably give the game out for free on the site, since it's my first "product." So far I'll be drawing the maps and will be soliciting people to draw pictures, but I would appreciate any tips on making a good system.
