Old World is such a good game everyone should stop playing civilization and switch to Old World
Seconding this. I feel like Civilization's lack of focus causes most of its problems, so Old World focusing on a more specific period of human history fixes a lot. The only issue would be if you don't care for the specific time period, which is pre-history to the early medieval.
As for the fantasy recommendation in the tags, I haven't played the sequel yet but Endless Legend 1 is amazing. I might recommend Age of Wonders 4 over it, depending on what you want from a game: Endless Legend has slightly better gameplay with more interesting base factions, but AoW 4 has a really fun fantasy faction creator with a wide variety of options, both at start up but also as you research spells and other tech. Whichever sounds better to you, you're probably right.
Age of wonders 4 is great, but i prefer the combat in EL (like...a lot)...also EL1 has lowkey the only good 4x naval gameplay imo
And endless 2 has a fantastic system where more and more of the map is unlocked in segments
