I'd bet money it'll be "simple" but with a load of optional rules (which I'm guessing will be included in the second-tier book he hinted at). I'll get in on this if one of two things occur:
1) It goes ballistic and becomes a good value for money.
2) It has great minis. I'm normally quite soured by Mantic stuff, but the ones shown in the video are quite nice.
As with the 25th-Ed. Hero Quest, I won't likely be buying it to play the game itself but rather to get a big box of minis. I'm not overly excited about the idea of the PVC style material - but if it's a good kickstarter I'll throw in on it. I'd also imagine the basic Kickstarter should be what $65-80? A starter box shouldn't be much more than that. Nice to see the aim at dungeon crawling though. Colour me intrigued.
