I have tried making & playing a few custom maps.  Seems after the 5th or 6th NPC I recruit, the cost multiplier goes insane.  Jumps from a few gilder to around 1.7+ million.  I have seen some as high as 4+ million. 

I have been playing the test maps at Ridiculous (Yeah, I cheat).  Running the research speeds at Normal.  This still seems to just blow through the spell & tech research at an alarming rate (with very few Ancient Temples or Lost Libraries).

Anyone else notice if the internal mathematical algorithms seem "off"?

Thank you,
