The game's not about just preventing things, though. It's also about managing things, preparing for things, and reacting to things. Anyway, this game badly needs changing conditions - like, really badly - because the final 1/3rd to 1/2 of every game is tedious and predictable. Until R&F came out, I hadn't finished a game of Civ VI in a year. I recently played a game through to the end, just to see if R&F had improved the dynamism of the back half of the game (it didn't seem to, but it was just one game). I'm also a historian, by avocation only, and I'd love it if this game asked me to actually do something past the Medieval Era. Most of the current problem is with the AI, but I'm sure programming an AI that can keep pace with a human is pretty tough. Throwing curveballs at the player would improve both historical accuracy and gameplay. Anyway, there's no reason some sort of "disasters" or "events" system couldn't be an option you can turn on or off when you start a new game.
