The only thing I really found fun on GTA V was stealing a Hydra and then blowing everyone up...

And now that they stopped GTA:MP from going ahead, GTA V has nothing going for it, so glad I never bought it for PC.

Apparently i did not miss anything so special from GTA V..still haven't tried it once 
It's all a bit meh, sure the huge map is fun to explore at first, but that's about it.
