it definitely needed some more polish time.
It is very buggy and slow paced.
Buggy as hell and the ending is horrible, but otherwise, this is a great game!
8.5 is a fantastic score. It is just for such a huge game with insane amounts of hype, some people are going to be disappointed with a score of 8.5/10.
For Comparison sake,
AC: Brotherhood (La Hermandad) 8.5/10
