I think the only reason I was a bit letdown by the scores initially is out of all the current gen exclusives that have come out to this point between the PS4 and XBO, Second Son is the first one that has me saying "I'm probably going to need to buy this whenever I get a new console". Nothing from these reviews has swayed me from that opinion, but I guess I just wanted to see higher scores (Metacritic in the 90's), because well, who doesn't want to see a game their looking forward to be critically praised to the highest level?
But truth is, it doesn't really matter to me. I'll look forward to playing the game whenever I buy a PS4, and expect to have a good time with it. I'm glad to hear a lot of places calling it the best of the series, since I enjoyed the first 2 games a good deal as well.
