I voted KR 25% of the time, I mainly use it for crafting and mining
I'd use it more if the graphics were better/crisper. I know that leads to a whole other discussion, but to me everything blurs into everything else, there's no definition between tree/grass and when I am moving around with that, I end up nauseous =)
I DO like KR, I think the macro system is excellent, I just can't play it and move at the same time =P (slight exaggeration =P)
*edits* I should add, I actually *like* a lot of the artwork in KR, I like the way stuff looks, but I don't like the lack of definition. And the perspective seems wrong somehow, everything looks smaller, and... odd
