You can make a perfectly fine game out of Swords, Bows and Horses. Hell, I'd argue Disco Elysium proves you can get away with less.
I feel like you didn't understand what I meant by that. I think ASOIAF is too similar because it's still basically high fantasy just grounded in a faux-historicity. What I want is to see Larian take a crack at a genre besides traditional fantasy.
