I have very mixed feelings about Civ 5 after ~200 hours. I started with BNW but it still never felt quite finished – the tech pacing & unit balancing always felt a bit off; the AI, trade, & diplomacy felt unfinished; and multiplayer was a flaming dumpster fire (we had to scrub a game a hundred turns in when it deadlocked, and their support took 3 weeks to say they didn’t support Macs and close the ticket (it was running on Windows)).

There was so much polish in other areas that it was odd that the rough edges were never sanded down. The bad AI & especially diplomacy were one of the most immersion-breaking experiences and unlike some of the other tweaks they haven’t been well solved by community modders.
