I tried to complete it on the original version (3.1) – it doesn't work because: the hero at the beginning of the game is extremely powerful, and it's impossible to defeat him. If anyone has managed to defeat him without using cheats, please post a video or save file. It can be completed on EVE because the enemy hero who appears at the beginning is weaker, and there is a chance to add strong neutral units to the hero's army. It is unclear whether this is a coincidence or a bug, but the possibility exists. I should also note that some scripts didn't work for me, but the game didn't crash!

ass1952, did you play the original version of the game, or with third-party mods installed?
I confirm... it is indeed much easier on EWA because a lot of mobs join you. But there are also some drawbacks (my sawmill guards were invulnerable for about a week – a powerful force was stationed there – alternative dryads)
