Divinity: Dragon Commander is an interesting hybrid. It has RTS, Grand Strategy, RPG and shooter elements in it.
It offers everything, which is one of it's main flaws. While it does everything, it doesn't excel at anything. However, the way this all comes together makes it somehow work. At no point do you feel "I need more this" than other.
Strongest part of the game is the cast interaction onboard your command ship, Raven. Ranging from personal drama of your generals, to small scale political incidents by politicians to deciding national policies all the way to your personal love life. This is one of the most interesting aspects of the game and despite the binary nature of the decision, the sheer amount of branching is sure to keep you interested. Especially when it comes to your queen, who all have their branching story lines.
The weakest part of the game, is the RTS section. While there is depth to be found, it sufers from the weak UI. There is no auto-cast, which makes certain units near useless, as they require micromanagment. Management, which you can't do due to UI. Most battles end with one side achieving early dominance and then grinding the opponent down. Of course, when this happens to you, the dragon form you can take can change the course of the battle. AI tends to rely on zerg rush, though it can some times surprise you.
Strategy portion is your standard, build units on the map, move them, build structures and research tech. Nothing complex, but it has certain depth to it once you get a hang of it. Main issue is the AI.
Indeed, flying as a dragon is fun, even if it makes managing your army harder. Some people complain of the shit limit you have, but I believe it is a good way to counter the power of the dragon. Furthermore, it only counts in term of firing rate. I found that my not clicking as fast as I can, and instead simply holding the mouse button, I could keep up steady firing rate which lead to my breath weapon cool down faster than it would heat. This is useful, since you can do quick initial damage barrage and then steady shooting.
Overall, the game excels at nothing, but it goes above average at everything. While the story campaign is relatively short, it is enjoyable. There is a lot more to write, but the word count looms in the horizon. I recommend this game for everyone.
