Just a few loose ideas.

Instead of todays longbows, Man should have javelin-throwers with atl-atls - which should give them a range advantage over Ulm's more powerful stone-throwers.

There should be a nunatak special site wich gives + to production. Various glacier-based sites, ice-caves, frozen water-falls, deep-frozen lakes et. al. for other site "themes". Volcanoes, hot-springs and magical fire sites might add a few +1 heat dominions.

Instead of Marignon and Arco, perhaps nations based on Inuit and Lapplanders? (Polar-bear mounted heroes bravely battling masses of spear-throwers fighting from sleighs drawn by reindeer.)

R'lyeh should be land-based in this mod (Re: At the Mountains of Madness) Perhaps even a pre-fall Atlantis
