Sorry--I misread the bit about sieges and starving...
But here's a few inaccuracies with the game--as I see it:
1) Firstly, and most important-- the UN has power.
2) B2's on carriers? And they only have a range of 200 miles or so further than a WWII-era bomber such as a B-24 or B-25?
3) The timeline position of Democracy and Shakespear's theater.
4) The game's handling of choppers
5) Lack of lethal bombing/bombardment from air, sea, and artillery units.
6) Units, once united under a leader and taught how to work as a group, cannot recieve better weaponry.
7) A country, armed with musketmen and medieval infantry, attacks a superpower with bombers and tanks. 9/11 aside, as that was--at least overtly--a private endeavour.
8) Privateers cannot bombard
9) Privateers cannot loot (this is, after all, why countries such as Spain, England, and the US comissioned them in the first place)
10) 2050
I realize that some of the inaccuracies are necessary to make for stable gameplay and I, like everyone else, have suggestions as to how to improve what I see as problems. Yet the power of the UN to end the game, I think, is the most inaccurate thing out there, especially once one considers that the organization is little more than a social forum for diplomats that park wherever the Hell they feel like it in Manhattan.
So says me. Your mileage may vary.
Later!
