I play on Scribe level exclusively so far, for the same reason that I played exclusively on Settler level in Civ6: I want a peaceful game with no stress where I can just build up a nice looking empire. Civ7 is better in this regard than Civ6, but it's still far from perfect. IMO, on scribe level the AI should NEVER attack the player (maybe there is an option for that that I overlooked?). But I still often get war declarations by multiple opponents at the same time. Mind you, they are not dangerous to me (most of the time), they are just stupid and pointless. In Civ6 I could only really play somewhat peacefully by intentionally reducing the number of civs by a fair amount. Here in Civ7 I haven't done that yet, but I may try it.
It's strange really. In Civ5 I used to play on Prince or King level. In Civ BE I always play on the second highest level, same as I did in Alpha Centauri. Somehow these games have (or had) a lower annoyance factor. With Civ however (since Civ6 really), it feels like the devs want their AI to be annoying. I just don't have the patience for that anymore, so I look for more relaxing gameplay.
