I have tried the demo and I have to say that I like the feeling of the game (which is a lot since generaly I dont like RTS games too much, last ones I played were AOE, the very first, and warcraft I and II). Also I have to agree with Laars and Efrem that the resource gathering is different, more logical and simplified, even though I would have got rid of the stone and wood gathering part of it, IMO it adds nothing to the game.

I very much like the fact that there is fatigue, morale, limited ammo, considerable reload time, etc. Also unit experience and position (flanking, rear attack) are also very important which is an other good thing.

However, I think that there is one major weakness of the game, perhaps not surprisingly the AI. While head on it can be challanging and sometimes even outright impossible to beat, it becomes helpless when it comes to protect its rear and its resources. In the skrimish battle I conquered the AI villages one by one with a single battalion of fusiliers and the AI did nothing! It kept throwing his units against my prepared defenses without sending a single unit to protect its resources! Of course the predictable outcome is that it ended up boxed up in the upper right corner of the map around its barrack with dozen of useless, out of ammo battalions.

If the AI behaviour is the same in game (and why should it be different?) then IMO the SP part of the game is close to useless, despite of the more or less realistic and highly welcomed morale, fatigue, ammo system.
