Got my core set a couple of days ago and after sifting thought the rules and contents sat down this afternoon to take my first run with the game. I did the learn to play mission and then read the skirmish rules. Honestly, I'll probably never play the campaign stuff. If I want to do that, I'll just dig out my d20 RPG books. It was the same reason I passed on Descent. Why wold I want to play a limiting combat scenario when I can get far more flexibility in full-on rollaying? Maybe as my kid gets older, this will be a fun distraction to ease him into RPG gaming, but that's a long way off.
But the skirmish game on the other hand....
I've been excited for this from the moment I talked to the designers about it at GenCon, and the rules for it do not disappoint. It looks really well balanced and offers the tactical component the old WotC game seemed to miss with its beer and pretzels approach.
