After a game where Basium, and Einon turned neutral thanks to OO, while Alexis and the Clan turned neutral thanks to Empyrian, which produced together with Sandolophon, Arturus, Valledia and Rhoanna a complete neutral game, save for the Shaeim who went for AV and Bannor who went for the Order, I think, there are some arguments against the Alignment change...
The Order never spread near Basium - because Rhoanna was THE enemy of the Bannor and so they never had Open Border. AV spread a little bit to Khazad lands, but not enough to make the day. Ljoslfar went with FoL which spread to Rhoanna, but that's it. Kilmorph did not show up in that game. OO ruled the World (mostly) and there was a fierce fight between Rhoanna-Ljoslfar against the rest. Even the Shaeim went with OO before they researched AV.
I think there are several problems
- Passive Spread
- Civ's adpoting "wrong" religion
- Civ's just NOT researching new religions (when they already have one)
- Open Borders too early (offtopic: as well as Map Trading - they kill the explore feature)
- Civ's not adopting/spreading the religion from which they are holding the holy city.
Maybe it's because of the + diplomacy modifiers for the same religions but I don't think that's the only point.
The main problem could be, that some religions change the alignment only to neutral - Let's say Kilmorph would work like Order and make everyone good. Still this would lead to games with only good Civ's if everyone adopts Kilmorph. Therefore I'd say let the neutral AI-Civ's be able to adopt every religion. While the Good one's have a modifier of -50 against adopting AV and OO, likewise the Evil woudn't adopt RoK and Order. OR just increase the modifier for "you are evil" to about -6 instead of -2, so that they would not open borders. (and possibly remove passive spread if there is no open border?)
Empyrian, and Esus could be neutral, meaning they do not change alignments at all, but REVERSE them to the leaderspecific startup.
Something like this
Order, RoK -> change alignment to good. (there is an angel behind the whole thing)
Empyrian, Esus -> change alignment back to leader-specific (not so much divine involved)
FoL -> change alignment to neutral (nature IS neutral)
AV, OO -> change alignment to evil. (we're talking about demons here)
Good -> cannot adopt OO, AV
Neutral -> can adopt everything
Evil -> cannot adopt Order, RoK
well, just some thoughts, and still there is the problem of just neutral games, if Ljoslfar are in the game :/
