Some more information on the rules changes would be good. The original game had some pretty major issues. The fumble rules were just ridiculous, and the points values not balanced at all.
They are obviously re-using the original dice, which worries me, as I think the combat system had a fundamental mathematical flaw.
The original ToH is a game I regretted spending money on, despite its many good ideas. I would have to be reassured it has had some significant work to re visit it.
