After playing a few hours of GTA 5, I have to say that I'm very disappointed. Personally, I think Saints Row 3 set the benchmark for the most fun driving/shooting open-world game. I think Rockstar has consistently missed the mark by trying to make the GTA series more realistic. But who wants to drive cars that spin out of control all the time? And it's no fun running from the cops when missing a jump means suffering a 5 second long animation to get back on your feet. I'm sure a good argument can be made for realism, but I think some of these steps toward realism are also steps toward tedium.
What do all of you have the most fun playing: GTA or Saints Row?
