Action Adventure - between 12 and 18 hours
RPGs - between 40 and 50 hours
It all really depends on the entertainment package the game provides.
For example: RE4 was a phenomenal game, but it started to drag a bit by the end; FF12 took me 120 hours to beat and I'm left wondering why I logged such a huge amount of time in a game that bored me much more than amused me.
Then you have a game like God of War 1 and 2 that are just right, or FF10 where I logged about the same I did for 12, but it was a thoroughly entertaining experience.
Case by case basis is the best perspective, I'd say.
