RTS, Fun Factor
The real measure of a game is not historical accuracy or absolute parity; it is how much fun is the game to play.
AnA strikes a chord because most american males, at one point or another, enjoyed the game immensely. You don't have to look far for someone who spent too many late nights rolling dice.
RTS strikes this chord for one reason; my gaming buddy, spruance, and I can't get enough of this game. We've played about three online, and are hooked.
Good job, guys.
