Other than that, quite a steep learning curve, very low res units, no tutorial (the youtube videos by devs are absolute nonsense, you won't learn a thing). The animation and effects quality is straight from the year 1998.
It is also biased towards US and against USSR, and the scenarios are quite random, one small country can capture a giant one in matter of minutes just because it suddenly decides to. I understand it's meant to be random and you can edit this factor of "world volatility", but how on Earth could something like Laos bring down PRC with little to no effort in the blink of an eye?
It is, however, the only true global strategy game about Cold War period, so there isn't much choice on the market right now.
