Not really my sort of game normally. But I gave it a go since it was free on game pass. Started over a few times in the first 10 goes on metropolis difficulty getting to grips. Then the first time I really let it run, I was sprinting ahead with ease within 60 turns. Decided to go back and start again on Nation. Still won fairly easily, managed to box up the other nations pretty well. Rushed ahead with research and development at that point, and virtually cut them off from luxury resources too. Think only one of them was lucky enough to have any, and only basic essentials too, so they were really held back.
Quite fun, and played to the end (well, all science research ending, and a trip to mars finished virtually at the same time too), had attack helicopters fighting crossbowmen at best, generally ground units with no ranged capabilities, so it was a slaughter in conquest as well. Now uninstalled, people who enjoy the game I can imagine playing through in a variety of ways and enjoying it a lot.
