Hey guys. I've been GMing for a couple years now, and I'm finally getting good enough at it to break out of my comfort zone a bit. Now normally, I tend to run high fantasy adventures in magic heavy settings. Partially because that gives me the most wiggle room in world crafting, but mostly it's because it's become the only way I know how. After watching the first 3 seasons of Game of Thrones with my group, and delving into the book series shortly after, my group want to try a setting thats more gritty and realistic. I'm completely okay with this, but its not something I'm used to. So I was wondering if any fellow GMs have any suggestion or good home brew rules to implement. What classes and races should be allowed? What kind of monsters should they fight? What kind of special/magic arms and equipment should I give them, or should I give any out at all?
