So the one thing to be prepared for is the game is brutal fast. 20 life goes quick, and you never get all your dice in play. Most of our games are over in 15-20 minutes tops, and I maybe get to recruit 4-6 extra dice. Now maybe with more heroes the options for attacking/defending allow the game to last a bit longer, but I don't see it going more than 30 minutes. This isn't a complaint, but I had to shift my expectations that I'd be building my dice pool like you would build a Dominion deck - not the same. If one person gets out a few good dice, it's brutal for the other player. For instance, Liam loves playing with Wolverine, and he alone can do 10+ damage in one hit with a couple simple boosts.
All that said, I'll have my stuff at Games Day and can teach you the game.
