Tbh, if you want historical rpgs instead of fantasy one, we should ask for more people reading historical books instead of LotR. We also need someone making a historical rpg(that doesn't suck) to show people that one can sell this kind of game. No one wants to develop a long game if there is 0 proof it's going to sell, that is the true.
I remember how Sawyer said he took inspiration from historical events, yet he never had the opportunity of making a historical rpg, sadly.
