I'll be honest, I was a bit nervous when you compared your game to D&D and Shadowrun. Both have famously bad mechanics that shoot themselves in the foot compared to what the absolutely marvelous worldbuilding can do and are only the staples they are because they've been there decades ago...
But from a quick perusal this looks rather promising. I would love to commit some of my time to this project and its community but will have to see whether I can manage to free up some first. So, no promises at this point I'm afraid.
I really love the way you approach this, not as a commercial product but as hopeful community building. Can't give you enough kudos for this! :)
