Yeah, studying is a tedious thing, and replaying the first three missions is incredibly boring, but many people struggled with the fifth mission.
I only encountered one bug throughout the entire game, although I can't even boast about having a gigabyte of MB – in the Necromancer campaign, the third and fourth missions opened up at once.
Well, since people are complaining, it means there are issues; the developers didn't test the game thoroughly enough, they rushed it, that's for sure.
Andrey, are you saying that the rating is too high? Maybe. But you can't say that the game was universally criticized everywhere, right?))
