Depends on how you define "won", I guess.Antiquity, surely?
That's the same as it always has been though in Civ. I do applaud Firaxis for trying to curb snowballing, but even at release they didn't commit to it enough to make a difference. And they seem to be watering it down further. Other Civ games survived snowballing though so it is probably only a problem thanks to civ switching gating 2/3 of civs into irrelevant eras.
There comes a point in antiquity where the AI can no longer wipe you out, and - once you hit that - you know you are on track to get a win eventually. But I still make strategic choices through the first half of exploration. I'm still expanding. I am at the risk of not completing some of the objectives. There are specific wonders that I need to target if I don't want AI to grab them. In brief - it still feels like a strategy game, with interesting choices in the moment. But by the last third of it I'm done with those, and everything is on auto-pilot.
Modern can be won purely by overbuilding on the same spots, and pressing shift+enter. All modern wonders are easily gettable, and low impact. There's a small number of manual actions you need to take (or large number if you go for war), but they all follow strict script. You are not making strategic choices anymore.
