Although I agree that there are samey mechanics which at times can get boring, most of my games are rather different from one another.
I always play Deity / Huge maps but I play a different leader in each of my games and I turn on or off some of the NFP modes differently in each , so none of those have been alike, lately. Snowballed like hell to a SV with Dido and settling everywhere on the coast, grinded poorly with Pachacuti and Dramatic Ages to a DiploV after aiming too late for a RV, and succeeded at a pre-Renaissance era RV with Kupe and just 4 cities with the very first GProphet and by sniping every other religious civ as they created their own religion... So very different games and outcomes, none of which felt boring.
But I might feel differently when I reach 3,000 hours of gameplay, I'm just above 1,200 right now...
