Taking inspiration from Kenneth Hoods Grim n Gritty system, I've tried to cut out as many pages and extra rules and stats as possible, did a few additions of my own and called it Realismus.
It works with 2d10 and we've been playing with it for some time now. So here it is, perhaps you can use it as a reference or inspiration.
Feel free to use, comment, question, respond or utterly ridicule it...
I also added our Critical Hits variant.
Both documents are in perpetual beta though and I'd really love to hear your feedback (still thinking about using Margin of Success with Touch Attacks to negate Protection, for example)
