Is the game harder because of ToT and/or game speed?
I normally just play without much thought on optimizing but win easily on sovereign. I switched to online speed (now to faster) and went to immortal. These AI guys are suddenly cracked af and go into modern range with 70 science score while also going above 1.5k culture just waiting for the required points to drop and start the countdown at the end of exploration or in the first half of modern.
Also there is no shot for me to get wonders if I don't optimize for it. Any science wonders are built before I even research the tech.
I think it's game speed tbh because it takes so much production off and let them crank out wonders in 2 turns. (Saw it multiple times while "contesting" the wonder aka building it for 1 turn while needing 4)
Any experts on that field? Or do I have to tunnel more into my win condition and neglect the rest of victory conditions? (but I need to defend no?)
