Just started a new game this morning with this mod, and liking it so far. Only ~180 turns or so into a marathon game...
but. (you knew that was coming...)
There does seem to be something up with the repeat events as a few others have mentioned. I got the "choose the dorfs or the lizards" event 4x. So I have 6 dorf axemen guarding my borders atm, and would have 8 (assuming those 2 lived as well) except I chose the 'nope!' option.
Having the AC go from 1 to 12 on turn 2 scared the crap out of me. Then I realized it was from having the constellation change. Great idea! Would love to see more of this kind of constellation importance...I know that is on the wish list for the FF team. Not sure if they have started work on figuring out the constellations and their effects yet.
On turn 10, I found the Tower of Eyes, with Mind mana. Very nice.
Brought my scout to it, and out popped some humungous stone giant with a strength of 20. Not nice.
20? I mean c'mon, that's a bit much eh? Especially considering about 100 turns later, there was a 2nd one. No idea how the second one got popped, but I opened up the WB and deleted the roaming one

And do these Guardians pop on all the explorable featuers? Pyre, Sepulcher etc? Bleh.
Was pleasantly surprised when my Bird Tamer attacked a Gryphon, and morphed into a Gryphon Rider. 50 turns later, I had circumnavagated the globe. Nice touch though
Oh yeah...and why can't these elves (Arkitan...) not create improvements on forested tiles like other elves. I might be making my very first non Fotl elven civ at this point. Really don't feel like chopping all that wood, and then replacing it all with blooming Priests.
Anyways, perhaps those Guardians should be toned down some...20 is pretty insane at any point of the game, but especially in the early going. And it takes a fairly important resource (even if it is a 1 use resource ala Ffh, instead of a repeating use ala FF) for all the civs in the early going. Those early Sages, Bards, Commanders etc can be really really important if you are lucky enough to get them.
Anyways, enjoying it so far, the good and the bad. Some great ideas in there. Thanks for making this!
