As a starter package this is rather good. Although the packaging recommends for ages 14+ there's no reason younger players familiar with trading card games or other tabletop strategy games should have any problems with the rules.
All character actions and abilities are rolled on one or more d10, six of which are included in the package (three red and three blue), 3 or less is a miss, 4 upwards is a hit and 10 is a critical. Magic resistance is simplified in comparison to the PC or trading card game, all schools of magic are under one resistance heading. There's nothing more complex than the Fighting Fantasy or Dungeons & Dragons I enjoyed at a young age.
The models themselves look fairly good bearing in mind the cost, certainly on a par with other licensed collectibles. They do have the odd twist on the weapons but it isn't detrimental in any way to the game itself.
Players of the PC game will immediately identify with the streamlined nature of abilities and whilst not essential, experience of the PC game itself will give a better understanding of how best to use the classes.
All in all this is fun, accessible and reasonably fast to play. The rules suggest that the first time you play to ignore the extra ability cards included in the package and play with the abilities on the character cards alone. My advice to anyone with experience of the genre is to disregard this suggestion as the game feels incredibly limited in doing so.
It's worth considering getting some booster packs or to look for individual models to bolster the initial characters included (Draenei paladin, Gnome mage, Orc warrior and Blood Elf priest). Although there's no reason the starter box can't be enjoyed as a standalone package, it did feel a little limited after four or so games. The manual even recommends using more characters per side. It also might be an idea to dig out some spare d10 if you have them to keep things moving at a decent pace.
