How long do you want games these days to last???

Edit-title should be "how long do you want games these days to last???"
the former sounded kinda sexual lol.
\Excluding the ever long rpg genre, how long would you like your genre's game to be? To me, no matter how good a game is, i'd like to it to end so i can get on with my life and accomplish other things and beat other games. Are games getting longer? This day and age, a 15+ hour game is typical, minus cutscenes. I'd rather it be 8 hours or so, make it replayable and to the point, and NO BEGINNING TUTORIALS. If i want to know how to play the game, i'd like to have an option in the main menu for this. It would help with the surprise and mystery instead of things being spelled out all the time like a color in the lines experience. Off topic for a second, a real next gen rant. Wario Land Shake It is just ripe for a 6 hour jam through so i can get on with my life. Hows about you?

Action:6-7 hours preferrably
