I captured the Elven Castle and defeated the demon with the Necromancer. I also collected a couple more artifacts for the quests. I didn't finish playing. There's one unfinished castle with a weak growth rate, plus several miscellaneous dwellings. At the same time, I need to defeat many legions of neutrals. It's a static routine with a long accumulation period. The monotonous demon raids only prolong it. It's just not my style, but it might appeal to someone. Everything works, no bugs were found in the completed stage.

Okay, I'll try to play it and report back; but not soon, I'm short on time.
