Its completely different story.

Kinda kills me that people focus on the ending of 3 when all the games have been pretty great. That ending doesn't define the entirety of this series.

I didn't care for the ending of 3, but it didn't take away from the experience as a whole that the series has given me.

I'm copping this one because the others have been great. Despite the animations being less than desirable it almost feels like there is an unfair internet dogpile on this game that most of us haven't even played yet, or have gotten that far into. I'll judge it myself.
