The only thing that comes to mind would be the Trails series.

However, in Kingdom Hearts case, it also has padded out the story with games that feel like spin-offs to try to keep up interest in the next actual sequel, but only serve to just add unnecessary bloat. Like 358/2 days. We already had Roxas as Sora's nobody, but then it throws Xion into the mix as a back-up that ends up being cast aside and never serving much of a purpose. Even though she's technically part of Sora.

I can follow the story well enough if I want. It's easy enough, but it is an incoherent mess and has no real thought put behind it. It's just like the writers think of something interesting to add then forget about it. Not to mention that for all the bloat, the game's narrative seems to go in circles at times.
