Just a few things I've thought of while reading this,
1st: as I have not played the Sheam how do they get a bonus from high AC besides there portals summon better demons? Or is that it? If that's all they get its still a big price to pay for having allot of your health and happy items go away (they all turn into one of the 3 hell types).
2nd: Maybe add a mechanic that is along the lines of the influence driven war option: When an evil army marches into a good land and pillages / fights it spreads hell tiles. The good side already has a way of cleaning the land but evil has no way of spreading it, to give there demon units a boost.
3nd: As of now hell tiles give daemons a big boost and that's all well and good but maybe expand the system so any unit with AV religion gets the boost as well? (not sure if theirs a way to track if units are built by evil or good civs and thus the units them self's are good / evil so might have to use the existing unit religion mechanic). Maybe just make it so hell tiles nerf any living unit, that way demons (there home landscape) Angels (what they trained to fight in?) and undead (witch helps evil mostly) can be the weapons of choice, would also give the dwarfs a round about boost as allot of there units are not "alive".
4th: Maybe add some new resources to hell tiles, ya sure hell might not be the best place to find items that make you happy / healthy (like how the current system works by nerfing those resources) but there are probably some really nasty things to make weapons out of (daemon bone weapons or something) and some nasty nasty critters to use as weapons, this is already party in place with the night mares, how is a Knight on a flaming daemon horse that is mostly likely a deadly foe without a rider the equal to the same type of Knight on a normal horse?
