Just reading through the Heroes book now. Which is basically the DM+PHB combined. There are a lot if ideas here that I like. It's a 2d10 system instead of d20. This means your rolls are on a curve.
You always hit with abilities, and rolling is about how powerful your hit is. Each ability has three tiers of outcome. A T1 outcome of a weapon strike might do a little damage, while a T3 might do a lot of damage and push a monster 2 squares away.
I love the idea of never missing. I imagine it puts the combat on a real clock, and likely makes the monsters feel dangerous and lethal.
That's only the tip of the spear, and I'm still reading. Anyone else giving this a read?
A lot of DND combat can become slugfests where once everything is in position, no one moves unless something dies. I love the idea that this game is more mobile, with faster combats, and less frequent resting. The resources you only ever care about is your stamina (HP) and recoveries (which you spend to heal). So you are never holding on to resources for the "right time". That's the impression I get anyway, having not played it yet.
