I played Age of Sigmar yesterda and I had fun
Is a skirmish light game who hide some in depth stuff (ripped shamelessy by other games, but whatever) and it's quite fun to play (and fast).
I never played it and I didn't even read the rules so well and I picked up everything in the first 10 minutes, the other 20 minutes I spent rolling dices happily and cursing when didn't get good rolls.
I don't think the game is worth the astronomical price they ask for the models, but if you already have models, why not.
