I liked GTAIVs realism though, that's why I would say more options to go mental, but not have them in the story. I'm playing Saints Row 2 at the moment, well, I started it. It seems a lot of fun, but it's technically poor, driving/running/shooting are all awkward. I much prefer GTAs euphoria physics quality - being drunk in the game was never more fun, shooting your own foot etc.
Trianglular Sandwiches advocate against remakes of games, except Halo MC collection and GTAV... and metro... and minecraft.
