First time in a while where I agree with Yahtzee at every turn. AC1 suffered from being repetitive as all fuck and I'll still argue to my last breath that AC2 was infinitely better. However, in Revelations and 3 we've now got to a stage where we've come full circle, and the side missions that were fun and refreshing in AC2 (and to only a slightly lesser extent Brotherhood) have now just become a chore.
I did like the new Homestead system though. Making the Homestead grow through characters that I could actually connect to, rather than just accounting, made it seem like a much more rewarding experience; and the ship missions are legitimately some of the most fun I've had on a console this year.
Actually, that's it! Ubisoft, don't make any more AC games. I'm a huge fan of the series, but the games I like will always exist now no matter what, and considering the attitude the last two entries have taken I can only see further games getting more and more bloated and convoluted. You've finished Desmond's arc now, and anything left in the story that remains unresolved isn't really worth making a whole new game around if all you're going to do is string us along with cliffhangers every time. So, end the AC franchise, and use the mechanics of the ship missions in AC3 as a template to give us a pirate game based entirely around that as the central mechanic. You literally could not take my money fast enough if you did that.
EDIT: Another thing about the last two AC games, which might sound minor but really niggled at me while playing them, is the look of the map in them. Why did they make it so dark? Why is it, even at full zoom, so far out? In AC2 and AC:B, the maps were both aesthetically pleasing to loo at, and incredibly simple to navigate, and it was little touches like that, how they managed to make something as small as just looking at the map feel rewarding, that made me love those two games so much. In AC:R and AC3, the maps are terrible.
