Yeah, it seems at a certain breaking point in the difficulty curve it becomes “catch up with the AI boni”, which made it a completely different game for me. And as you said, usually by renaissance you know if this is going to be a landslide victory (which at that point becomes a chore), or if you’re screwed.
I picked it up on sale after watching Fury Road, which in turn I put off watching for years because I really like the first trilogy and did not want to have that memory tainted by some cash grab Hollywood sequel. Boy was I wrong about the film, and I was equally blown away by the game, to a point I felt really guilty getting it for 10 bucks or so. I really, really wish there was a multiplayer, though.
