I'm with Turfster on GTA V. Every open world game has a point where driving around the city listening to the radio stops being satisfying. I hit that point earlier than normal in GTA V, and then there just wasn't anything in the core gameplay to keep me interested. The mission design is absolutely atrocious outside of a handful of decent heist missions.
Maybe I'll go back and finish the game some day when enough time has passed that Los Santos feels fresh again. Maybe.
Edit: It's not that GTA is necessarily bad. It's just overall burnout on that style of open world game, and them not really doing enough to shake up the formula (character switching is a neat idea, but it overall doesn't fix the problems). It's the same issue with the Assassin's Creed series. 2 was great, and so was Brotherhood. Revelations started to drag, and by the time I got done with 3 I just wanted nothing to do with the franchise until they make some drastic changes.
