how many hours do you think i could get out of playing black and white 2 randomized over and over before it gets old?

im looking for ways to burn time. its something i could play in bed, out and about, anywhere. its not buried behind a load of dialogue like sun and moon are sadly. its something i could play on the side while doing things like watching tv. it doesnt have xp all sadly so there is some pacing thatll be held back.

thoughts?
