If we consider the option of breaking through the garrison, we can break through the first one, but not the second or the rest. What's the point?
If we follow the storyline, then yes, we can complete it linearly. But then we lose the alternative ways to complete the Walkthrough (if we play fairly and without cheats).
This is all on Hero difficulty.
4. I mean the option for the player to be able to reach Ayven without completing the quest for the monazite sand and weakening Dominick. Because when I played, I created a pretty decent army using necromancy and the undead converter, and I didn't see the point in weakening Dominick.
Or maybe I missed something?
