I haven't played since 7th edition was first out 
Never even heard of Age of Sigmar up until now.
Age of Sigmar just came out, they don't even have all the base rules yet. Didn't stop them from selling a starter box, but whatever.
It's a completely different game, enough that the Fantasy crowd here had a major hissy fit, talked shit about Games Workshop, and have since stopped playing completely. My friend, who owns the game store I frequent, has never seen anything like this from the GW community, he says.
I tried it, and it was fun. Not balanced by any means, but still pretty fun. Best part is, the rules are free for now and forever, and it doesn't care what your models are as long as have something appropriately sized.
