The biggest problem with the series is stagnation. Anyone that has beaten Origin, Odyssey, and then Valhalla, was probably feeling that towards the second half of Valhalla. I know that I was. Despite the polish and solid story, it became somewhat of a slog. This is the same problem with Far Cry but FC feels far more stagnant as I felt 6 was a fucking slog and only finished the game so I didn’t feel like I wasted my money.
Ubisoft needs to really take a hard look and change up their formula. I feel like some of Sony’s first party games are trending down this path as well, we are probably a couple more releases away from feeling it, at least I am.
