This game is sort of like Warcraft-lite, in a sense. It's been years since I played it, so my memory might be hazy, but I did play it to completion and remember it being serviceable, if a bit buggy (IE, one map required me to defend a building with my Hero unit and a few basic infantrymen, and all of the infantrymen died, except for one that somehow got 20 levels ahead of everybody else and became death personified). If you want some kind of RTS-lite type of fantasy game to amuse yourself for a weekend, then go for it, and if you don't like it you're only out ten bucks. Otherwise, stick with Warcraft or Spellforce or something.
I'll reccomend it, but it's sort of a 'meh' reccomendation than a "ZOMG GET IT NAO" one. It works and it's amusing, but other games have done it better.
