Yeah just checked, from 2009 to 2015 they released like one gamer per year, and it's not like ac games are small games to make, they are huge open worlds.
True, that was when they had one more team to cycle those developments, to my memory it didn't take one year to make, merely that they had a rotation of teams, but even that cycle was a pretty rapid one for the type of game they were making.
but after AC Unity, that frantic type development took a toll and they were correct to remove one team and make that development a bit longer to maintain a level of quality.
Even as a massive Sony fan, I don't think Sony has a team that has ever even put out a game as massive or as complex as some of the ones Ubisoft have put out, so

is correct, its easier in comparison to polish smaller games that are more controlled
They put out some massive titles, I think with have complex gaming has become, with Unity it just caught up with them (semi OT, I hope we get a remake of that in the new engine)
i like the choice they made in Valhalla to have England, France, Norway and Scotland
I think with AC Hexe, its likely they may have many countries as I think the on going rumor is that its in Germany or something.
