I have a confession - a lot of my enjoyment of this game was out of spite. To get more information about this game, I decided to look at a Let's Play (http://lparchive.org/Beyond-Divinity
). Some information is good - for example, sneak is absolutely invaluable. Some I'm unsure of, like all the skills he calls useless. One thing I know for sure he's dead wrong about - magic. Magic is wonderful. Magic is incredible. Magic can break the game in half, especially with the wonders of Hammer. Summoning dolls I'm less sure about, but I think they're worth more exploration.
To me, this game really hearkens to Warcraft 2 - the music is really reminiscent of something you'd hear during the Orc missions and the cartoonish graphics are similarily familiar (maybe Warcraft 3). It's got RTS-lite gameplay where you control two party members, each with their own skills and stats, with the option to summon more temporarily. The comically bad voice acting is comparable in tone although not in quality.
I do have one big problem with it, though. If you click on the wildlife by accident, -all- wildlife of that type aggro you. There's a lot of wildlife. It gets tedious.
Overall, I'd say give it a whirl. It's a fun adventure and continuation of the Divinity plotline. I'd also recommend reading the included Novella, Child of Chaos - it's a short read that sets up the plot of the game and makes later events make a lot more sense.
