I have played all arkain books , and they were all great but a small issue was that my ai was very bad compared to enemy ai.
It sends a small amount of units and rarely , making ai just defensive and not offensive at all. In the last mission of second orc book the ai was good and it s like it should be each chapter.
Would wish to see the allied ai smart like the enemy ai in a lot of missions (Mostly in second orc book).
But ofc this is just a suggestion. Great campaigns man , can t wait to play second undead book!
By the way , you should make a discord group
