As someone who has generally always played epic/huge maps as epic is always 1.5x speed and huge is always 1.5x map size and is using the same settings for civ 7 (got a mod for huge map sizes) along with long ages, i am finding those settings to be very quick gameplay wise. Playthroughs used to take me weeks to complete with previous games and i am now completing games in days.
When i did my first run on all standard settings i did the first age in a couple of hours and this was with low difficultty and me having no idea so barely any of the legacy points got triggered.
With more experience i am now trying to prolong ages by gaming the system to not trigger legacy paths until the last turn if possible.e.g. in antiquity, having a settler sitting waiting to create a new city on the last turn, getting all the codexs but waiting to the last turn to buy a library to put the last set in so i can prep better for the next age.
After my first few games i always turn off the crisis now as it wasn't really adding anything to the experience apart from pointless micromanagement and annoyance and seems more like one of the scenarios they adding in civ 6 than a good core gameplay mechanic. Considering how unfinished the game obviously is the devs must have known the crisis wasn't a vital part of the core gameplay and actually took the time to add an option to turn it off. I just wish it you could turn it off permanently and not have to rememeber to untick the box each time.
