wargame is not AoA. wargame is better. i've played AoA a bit, and all i get out of it is this world of goo feel were i just build units to A-move, yeah sure you sim city to death as well. but its just not interesting one bit.
I find it lacks the depth of a good strategy game. all your units are mostly passive and that generates a lot of free time. which makes the game uninteresting. Unlike for example starcraft you have all these really awesome caster abilities where half the units can do pretty things.
In all i'd rather play stronghold crusader 2 over this game so far, and that game isn't close to as good as it's counterparts. but still i find it more fun and it stretches in how challenging it can be.
Honestly if you want to go for a game that is closer to AoA or world of goo but far better in all aspects play supreme commander forged alliance. It's more gratifying to win in a game. there is even a scene for such a game if you really want to go and join that community.

It's smaller but I can just say that it would hold anyone a lot better then AoA for those who feel bored of CoH2
