I've come to the conclusion that GTA just isn't for me. I loved messing around with mates originally on the PS3, but I hardly touched any missions (story or otherwise) and just robbed offies repeatedly.
Far Cry 4 on the other hand, I just can't get enough of. It really is the best looking game overall that I've played on my PS4. Drive Club was extremely pretty, but overall the environments of FC4 are just so nice to doss around in. I'm now 52 hours in, 48% completed and I haven't even touched the user generated content yet.
My game of this generation so far without a doubt.
