I'm pretty sure I won this scenario - I killed my 100 units, protected Bourne the Gleaming, killed Hyborem, and razed all the Infernal cities - but it was all just reported as a conquest victory for Basium.
Other issues:
- There was an ocean square near Bastradam where Ira kept spawning, so that by the time I sailed over and checked it out, there were something like ten Ira on the one square. When my army got close enough, all ten came onto land at the same moment and killed my forces. I parked a ship there the next time I tried the scenario, which prevented the Ira spawn quite nicely.
- The Lanun player starts off without Bourne the Gleaming in the visible territory area, and so has no idea where it is. You can't move units west to find it either. I was only able to find it by using floating eyes. It's really hard to protect a city you can't find.
- I parked my Arcane Barges right next to Bastradam and used the fireballs to pick off a weak Infernal unit each turn. That gave me about a third of my 100-unit quota. It felt like an exploit, but I can't for the life of me think of any other way the barges might possibly be useful.
- Very minor: in the event text where the demon offers to ally with you, there's the word [PARAGRAPH] instead of an actual paragraph.
- Right before I got my 100 units: "This scenario was pretty easy". Right before conquering Bastradam: "This scenario was kind of hard, but nowhere near as crazy hard as the Momus." Right before killing Hyborem in Dis: "This scenario was crazy hard, but not sadistically so." And then there was Despero and Poena...
- I assume the storyline involves the Mercurian Gate being finished once you've killed your 100th unit, because Basium and his angels started pouring through then. But I never got any text messages telling me that was what was happening or anything.
