Having fun with this game but no undead is knock against it in my opinion. I just don't think limiting entire races should be part of the game. You always got to choose what you wanted to bring with you and play the renegade if it was fun for you.
But no undead or lizardmen... that's a significant part of what the game has to offer, imo. Are they just holding back to make a Crossworlds-like version of WoTN? I hope they do, because I want it ALL. All the spells, all the units... bwa hahaha. Plus I have all these points in those abilities which decrease intolerance and raise morale. I took all those diversity classes for what?!
And I know I can mod it in, but it's just not the same for me as when it's woven into the game naturally. Having said that, a mod to put a selection undead into various ghost ships would be cool. Not all of them in every one, but rather like the other dwellings you could slowly put together an army based on each ship you clear.
Edit: Oops, you can get demons
