This game is well conceived, poorly executed
I was having a decent time. At first.
I think it was the 4th level in the campaign that things became bullshit. The enemy units are either too strong or they are too easy for the enemy base to purchase. If the units are balanced, then the AI system is not. In RTS games like warcraft and starcraft, the advantage the human has is better decisionmaking than the computer. While they are better at controlling many units, this game rules out that ability. There's virtually no thinking involved in this game. You pretty much just spawn what you can and try different combinations of units, none of which work.
It's just frustrating and really sucks any kind of fun out of the game.
