It could very well be that Rockstar North are taking themselves way too seriously these days. I know GTA is North's baby, but I honestly believe they should start rotating the franchises around their different development teams, as familiarity breeds contempt. I mean, they all work on each other's games anyway. Would it really be so terrible if San Diego created the next GTA? The Houser's & Benzies are creative leads on most of the games anyway.
For me, RDR was their most outstanding game last gen. V was incredible, but I think they need to mix it up with this new generation.
