Looking at the achievement dates, this took me 14 years to complete. But there was over a decade between sessions. I do realize why I gave up on it though. The gunplay is stellar, at least on release, but the rest is mostly nothing and a lot of it. Way to many missions where you shoot a couple guys or pick someone up followed by endless driving. Often taking you across the map and back for little reason other than padding. And the driving is far from good. I really don't understand why these games are even open world. It makes for a good backdrop, but with the missions all being connected, I never explored the world at all. Just drove to a gun fight, then back home to get to bed and repeat the next day.
