General gameplay tactics and its features.

I play with the "strong monsters" setting! And imagine that all the mines are guarded by 40-60 level 1 (if you're lucky) or level 2 units! Where do you get resources?

I also play only with strong monsters. And so what? Everything is fine. The main thing is to capture the lumber mill and quarry. That's it. Then you chase after the capitol. And so on. You have a minimum of a month to build up on this difficulty. Often, it's much more.
