I love Pathfinder but I am a bit tired of kingdom management. I avoid it at all costs in pen and paper d20 gaming. Too much work. I'd rather be a roaming problem solver (or creator, depending on my alignment).
So I'll hold off until I know more about the "King" aspect of Kingmaker.
"If you want to back the campaign and receive a copy of the game, you’ll have to pitch in at least $25."
Make that $28. You could actually get it for $20 if you were in early enough (first 300, all gone). The $25 tier was only for the next 1,500 backers (also gone). So it's $28 now - imo at least $8 too much for an unseen shot in the dark (especially if recent Kickstarters are anything to go by).
