Overly simplified - complete disappointment
Basically, all they did here was removal. They removed almost all units and added one or two experimentals. Structures are gone as well, out of an amazingly wide choice what you wanted to defend or attack with in the first 2 games, all you get here is the simplest possible machine gun and anti air turret accompanied with a heavy long range cannon. Research system is ruined, same sh*t like Command and Conquer and the resource system doesn't make much sense either. There is no more connections between structures thus the simplification was a total success if you ask me.
The research system could be a good idea also, but personally I don't like it. Health, range and other boosts seem decent but it just isn't what Supreme Commander is about!
I cannot understand what did they want to accomplish with this, it seems like they went a step backwards, like they intentionally wanted to fail. It looks like this is the first game, not the third one, that was supposed to make us play even more hours and fight greater battles than before. Dear Square Enix and Gas Powered Games, how do you expect us to play this game more than the previous ones with 8 units (INCLUDING experimentals) and 10 structures?
Total disappointment.
