The game indeed looks nice. But once the first impression fades away, you realize that it plays worse than Battle Isle 1 or Battalion: Nemesis or even Advanced Strategic Command (these games are either significantly less expensive or even free), The biggest downside of this game for me is that the UI is sluggish and not as assistive as it could be. As you play the game, you realize that it takes quite long, because you wait for something all the time (UI to respond, animation to finish, CPU to make a move). Note that I have a 2.9GHz Haswell i5, so the sluggishness is not about weak HW.
The story is not great, in-game popup story dialogs are not something you look forward to.
The AI is OK, sometimes stupid, ignoring you while you move around and take an advantageous position, but you are going to be grateful for that.
I don't recommend buying the game for more than $10 unless there is a significant patch fixing the issues above. The authors had such great examples to learn from, but they probably didn't play the game much. Otherwise they would have concentrated more on gameplay than on visuals.
Patch 1.1 update:
The developers have addressed some of the most painful issues, and the gameplay experience has improved considerably, but there is still room for improvements. What now stands out is the passivity of the AI The enemy has much more units at its disposal, but they basically just react to you when you start your offensive. Very sad when you compare it to Battle Isle 1.
The game is IMO worth $15 after the patch and the Battle Isle series is well recommended prior to Battle worlds: Kronos
