I think the story of San Andreas was pretty nice. It's very much scarface (in fact all the GTA's were like this).

The online missions of GTA V were terrible IMO. They're pretty degenerate yes. But the Singleplayer was nice. I also love the social commentary on US society. I really miss the roleplaying that people used to do in GTA:SA MP (third-party multiplayer mod) but of course rockstar had to go and kill it so they could sell their shark cards.
