Yep. I played an earlier version but it's the same game.
The key thing that made me notice was the scarecrow cards that allowed you to pick up your units, those make sense in Condottiere as it's divided in rounds where you fight multiple battles, so it made sense to pick up your units if you had excess power and were winning anyway, save your strength for the next battle in the round, whereas it made a lot less sense in Gwent given its 1v1 nature and fixed amount of rounds.
Mind you Gwent evolved a lot afterwards, I don't know much beyond the witcher 3 version, which I still enjoyed plenty.
The only thing possibly holding them off is that there's 2 or 3 factions all wanting to long knife™ eachother at the first chance, which means they have to be ready to go as soon as the power vacuum happens, and one of the factions controls the VP seat.
That might delay the chaos a bit, but not for long.
