Ok, so I just finished (quit in hysterical laughter) a "game" where I was trying to break the spell system. Or crash something. Never really happened, except a couple spells that I just couldn't cast (wouldn't light up once learned) -- haste, charm person, courage.
Oh and the Spellstaff spell is borked at the moment. Was using the Amurites, so my wizards start with Spellstaff. Casting it doesn't give you the spellstaff promotion, so you can't break it. And yet the spellstaff itself goes grayed out. Only way to get it back was to take it as a new promotion on level up.
But, failing to break anything, the meat of my post is just to amuse everyone testing. I know this isn't playable yet, but it made me laugh and cry a little.
"When Armageddon goes (horribly) wrong!"
So I'm happily Amuriting along. Basic techs, everyone's at the sword/archer/horsemen level basically, religions all discovered and active. Ashen Veil was really taking off, and suddenly Blight happened. Did it ever. I'm mostly used to blight. Sure, my cities had food problems, and health problems. Went to adjust them, but these were MAJOR problems. What happened?
Zooming out to look at the map (remembering that you can see resources updating even without line of sight, as long as you've explored) I figured it out. All the food was gone. Every single land-based food resource. Gone. And I'd say between 25 and 33% of the tiles went desert. Okay, when the end of the world starts, it starts big!
Well right there, this was gonna be a hooped game. But eh, we're just testing magic, I have a water node and plenty of adepts around, I can deal with this. So I fix everything up, plant more farms than I like, spring everything, away we go. I know the AI's screwed, but whatever.
About 50 turns later, we start popping horsemen. Do we ever. Turn 451. Barbarian spawns Stephanos. Barbarian spawns Stephanos. Barbarian spawns Stephanos. 6 more times... all in the same general direction (though not right together). Turn 452, I get the Stephanos story-popup, and they spawn another one for good measure.
3 turns after that, Barbarian spawns Buboes. Just one? Shame. End turn. Get the Buboes popup. Barbarian spawns Buboes. Barbarian spawns Buboes. Barbarian spawns Buboes. 5 more...
3 turns later, Faeryl Viconia is dead. Hey, I never met her, it COULD be coincidence right? 2 turns after that, Garrim Gyr is done. That's not a coincidence. He was right in the direction of those popups...
So I'm pretty amused at this point, and know I'm not gonna be able to check much more. I pop open world builder. The barbarians have the entire northeast of the continent. About 15% of the world's land already. Every town manned by a Buboes or a Stephanos. Oh, and Acheron in one.
It probably would have stopped there. They were all so busy guarding their towns, they couldn't take more. But i knew there were 2 (20) more Horsemen to come, and I quit the game laughing.
As a totally unrelated afterthought - BTS-style inflation is insane now. Inflation was always stronger in FfH than vanilla, but I was up to 115% in turn 450 (epic speed -- I was the tech leader, and just broke into macemen).
