My play sessions tend to last for entire routes. I might take a break to snag a drink/go to restroom, but that's it. I can easily play for hours on end, and really the session usually depends on length of route (which also often determines what time I finally go to sleep).
My longest play session (only broken by sleep, eating, other basic needs) was Muv-Luv Alternative - marathon playing all the way through it over a week.
