Someone put this video on the wiki and I was surprised to see it had a couple of retorts I had never seen before. This was evidently a beta version of MoM.
Far Seer
Omniscient
Special Race
In a later video, clearly labeled v1.0, these retorts are missing and have been replaced with the ones we know so well. In one of the screenshots, the starting city has a viewable area of 3 instead of 2, which is my guess as to what Far Seer does. Cool retort. It seems the entire exploring/viewing algorithm was smashed at some point hence Scouting never working correctly, so maybe that's why they removed Far Seer. I could see myself taking this in a game, at 1 pick it seems fun once in a while. Omniscient, I've no idea. Maybe grants Earth Lore or Awareness or those other map spells? Special Race is obviously what became the Myrran retort. Charismatic is missing, my guess is that Famous was deemed great but cost too much gold to use properly?
Stone Skin (Research cost 60) and Holy Armor (Research cost 130) both provide a +3 bonus to defense. Interesting, Magic the Gathering did the same thing I believe, offering identical powers in different colors but at different costs reflecting the differences in that color's philosophy.
Resist Elements works against Sorcery but lacks defense against magical ranged attacks.
Gnolls are depicted as building a Maritime Guild.
Gunther the Barbarian is 12 attack and 14 HP to start! And there is no "by five" separation of the rows of icons, making them hard to count.
