And Uncharted 4 could end up similar in quality. There's no way to tell until it releases.
Yer like the above poster said, we already know from a purely mechanical standpoint Uc4 is head and shoulders above the previous games based on the beta. It also has TLOU leads on it, who appear to be taking a lot of lessons learned from that game and applying them to this one.
Ultimately I guess we won't know until it releases how good/disappointing it ends ups being, but I think it is fair to have high expectations based on the knowledge we currently have.
