My 3rd game, this time v. 50d.
In the first 35 turns:
Turn 1 - Great Merchant created somewhere. Hard to believe the AI would explore a lair on Turn 1 and get this. I haven't received many Great Merchants from lairs, and exploring that close to your capital is not recommended - I lost on Turn 1 once when a lair popped a Skeleton inside my newly found capital.
Turn 16 - Great Engineer created somewhere.
Turn 33 - Mahala created a Great Prophet. And, here's where things go whacky. I was right next to her Scout and she did not pop any lairs. Also, I opened the World Builder and the Great Prophet was in Mahala's capital city. A mystery...how did the Doviello get a Great Prophet on Turn 33 (epic speed) and not from a lair?
Turn 34 - Another Great Merchant created somewhere.
Turn 35 - Another Great Prophet created somewhere.
That's 5 Great People in 35 turns.
How about me? Well, I explored in the first 75 turns 11 lairs and didn't get a Great Person. I got plenty of Gold, though. (there is an error there that says VILLAGERS gave me the Gold and that doesn't make sense). Also, more than enough Orcs coming out of the lairs, and I posted one very special reaction in the Balance Thread. Except for that last Ogre Explosion, my Scouts survived the exploration.
So, I'm still not convinced that all these Great People are coming from AI lair exploration. Especially the bit with Mahala's Great Prophet in my game tells me something is fishy here, but I don't know what it is yet.
