Lots to like about this system, its clean, simple and quick. Most importantly, its a fin game to play with friends and make some really cool scenarios.
My favourite part of the game so far is how Battle Shock works, its a huge part of the game.
If you've not read the rules yet (why not? They're free! [URL="Clicky click"]http://www.games-workshop.com/en-NZ/age-of-sigmar-compendiums[/URL]) Battle Shock is the morale system, its simple but plays out really well, if a unit loses models in a turn, at the end of the turn you roll a Battle Shock Test, a d6 and add the number of models you lost, for every point its over the Bravery score of the Unit, a model runs away from the battle and is removed from the table.
This means that as things start to go wrong for a unit, a few of them can start to decide to leg it, rather than as before where they'd all stand firm until it really got bad when they'd all break at once. You still have full routs possible, but this is when the unit is really taking damage, a bad turn can mean the whole unit bottles it.
I have found it a really cool system that works cinematically and yet is really simple and clean. Adds to the feel of battles with mortal units fighting in an age of Gods.
