I'm intrigued by the premise of Fortress America, and I am definitely planning on picking this one up. But one thing puzzles me, and perhaps fans of the original game can enlighten me. What on earth happened to Canada? I can see that the border between Canada and the USA still exists, so we're not supposed to assume Canada was annexed by the USA or anything. Yet we're supposed to believe that in the scenario depicted in the game, the three invading superpowers have no interest in first invading Canada as a staging ground to invading the USA? They all choose to simply ignore Canada?
I suppose the simple answer is "The makers of the game didn't want to bother with detailing a fourth invasion area" or something along those lines. But I find it hurts the game's verisimilitude somewhat to simply ignore Canada as if it wasn't even there. Unless you assume Canada is simply neutral or something, but even then it's hard to believe the invaders wouldn't pull a "Germany-through-Belgium" strategy to plow into the northern USA.
Thoughts?
