haha, good to hear. I hope you end up loving it as much as I do. You definitely have to put the frame rate up to make it playable, but yeah - I've never understood people who need amazing graphics in order to like a game. Of my top 10 games, maybe three of them have good graphics.
I generally dislike high fantasy also, but I think it doesn't bother me in BaK because I find the actual plot is pretty light on it. It's mostly a political story, and when high fantasy elements come into it it's usually minor or transitional. It's main role is as a gameplay element, either as magic in battle, the various magic objects like the spyglass, or the temple stuff.
Anyway, have fun. The riddle chests are probably my favourite part.
