I signed up for the game. But while waiting for my game getting started, I found this link for spectating and read the docs, and you know what, this is one of the least fun games one could design, imo. Otherwise they would show how it plays I guess, and everything. Look:
Let's compare to the game Risk. In Risk, when two armies fight, the outcome is randomized with dice rolls. Here the outcome is totally deterministic, the larger army always wins.
Another basic combat mechanics is Rock-Paper-Scissors (Age of Empires and many other strategy games used this mechanics). You could have three kinds of military units with their strengths and weaknesses. There is no such a thing here, you just have plain soldiers and workers.
The only potentially good thing about this game is the alliance part. Still it remains unclear does it really add anything to the game mechanics or not..
