When you choose Continent map style, the generated continents tend to be long/tall but not very wide. I really don't like this, I prefer the landmasses to be wide. Consider this map (it's not from civ6 but it's just to illustrate my point). I like the encircled landmass in the bottom left, not the one I encircled in the top right. I've had a few seeds that had wider landmasses and will share them here later today. I hope you guys can share some too if you encounter them, coz it's really hard to find these kind of maps!
