I'd say that arguably snowballing in Civ VII is the worst it's ever been, because now you get that period at the end of Exploration where you are obviously massively ahead, you know that you will win, you know how you will win, but - until you are allowed out of the era - you cannot actually progress towards it, so you are doing the equivalent of burning the tires in your sports car, spamming future techs & civics, stockpiling your traders, and your tech boosts, and your skill points, just so you can shoot out of the gate even harder at the start of modern.
If I had a snowball this massive in Civ VII, I could just get my sub-200 turns science victory and start again. No such luck here. And this is from someone that actually massively enjoys the eras system, because it does meaningfully break up the game, and the first 30 minutes of a new era is lots of fun little choices.
