In MTW, it was very easy to replace troops, that's why it was easy to take 2-3 provinces per turn. That is why it was a tediously repetitive game. The campaigns are all the same and the enemies all look the same and all act the same way. All you really do is go through North Africa. When you come out of the other end, you have already won.

It's the player vs. the whole collective ai very quickly, like it was a giant super-faction.
