Go figure. My first game of FF results in my first ever FFH game that I finished. Had my choice of victory conditions, elected for the thematically appropriate (kinda) Altar victory with the Mazatl.
Final thoughts on them:
The Order of the Wyverns -50% war weariness is incredibly powerful. You're right near Bannor Crusade territory, from a no-competition wonder. For comparison, Pillar of Chains is -10%, with side effects. I think this would still be excellent at -25%.
The Mazatl are agnostic, but while the Grigori specifically have temples/religious units disabled in vanilla I think, they can build them all, allowing them to spread all the religions to their cities, and more importantly given their incredible Great People synergy (huge cities), lets them fit in 4-5 more priests per city. I think all non-lizard priests/temples should be blocked.
I think in 0.31, Kael allowed priests to promote to Paladins/Eidolons. Since the lizard priests don't have a high-priest equivalency, it seems fair that they could promote to Paladins (Mazatl) and Eidolons (Cualli).
The hero was perfect. No hero trait for free xp, but enough strength he didn't need it, and the movement to go kill things easily. And yet he comes late enough to not overpower everything early.
Overall I thoroughly enjoyed the game, and the total differentness of the swamp mechanics. And bonus points to whoever designed the lizard mage-line, they were great (as were most of the units, but those really caught my eye)
Oh and one other thing I noticed late after conquering the Cualli -- you can't build a city on swamp (though at least your patch will allow me to scorch that away in the future)
More thumbs up Vehem -- think I'll go try a spider-game now, see how they work out!
