This game has only one flaw, it seems: identical sides. Why bother picking the Arm or Core...oh wait, the single player component is the reason. Beyond this, there are barely any flaws in balance, strategy, etc. When you construct your first Vulcan cannon (and have the resources to keep it running indefinitely), you will realize the true scale of a game-changing unit. In my opinion, the most useful unit is the flying scout you can build very early. It's cheap and acts as a disposable spotter for your long range missile ships/gun batteries/etc.
