You need to be a fan of the original as this one has decided that Tutorials are for sissies. I'm afraid playing a game that requires a working knowledge of MS Excel spreadsheets and flowcharts not to my taste. Did you not discuss Diplomacy because as I found, it is impenetrably difficult? Aegod's American Civil War is hard enough, but this is plain sadistic. If Grand Strategy is your thing, then Superpower might be a better bet. As for the tactical battles, which are very similar to the Hearts of Iron titles then it is better to look elsewhere. Close Combat: Modern Tactics is a better bet, bringing back the now classic squad combat in real time, only now set in present day conflicts.
Seriously, if you loved SR 2010, then you'll no doubt enjoy this offering. For everyone else, the learning curve is so steep, it is vertical.
