AAA games all share so many of the same common tropes that it will inevitably require spending a great deal of time doing the same familiar thing.
I've noticed this as well. Which is why I tend to avoid major titles. Nintendo has been doing a decent job, but still produces a lot of the same. Personally I like revisiting the Zelda series, so I keep picking them up. Even though I know it's going to be a lot of the same.
Indie games are pretty much key here. Each is unique and different, because they can afford to be. Major titles need to be the same to get sales. Indie games are much more free, since they don't require a million dollar income.
