I love the series so I have to enjoy it even I find some glitches or boring part or repetitive like the gameplay, yes they added new features but it is still like the previous AC.
I like the combat but I find it quite brutal and always mass murder. I can literally kill hundreds soldier without getting any scratches
But I really like the story of AC, especially when they release new characters, on game or even in the comics. I like finding out their history, background, who's their father, offspring, ancestors, etc. I want to find out what happens to Desmond after the AC3. and stuff like that... all in all I like the timeline of AC series.
One thing I'm curious and waiting now is the AC movie.
