I haven’t seen confirmation that this is what Ubisoft has been doing, but given how many studios they have and how quickly they turn games around, it wouldn’t surprise me if they used the “chase the sun” method of development, where as one team signs off, they hand development over to the next team, where it’s morning, and their work day is just starting. So it would just be very likely that every Ubisoft studio touches many games that Ubisoft works on. From the credits on their games, this is certainly what it appears to be. This is the same development method that Larian used to make a game as large as Baldur’s Gate 3 in only 6 years.
