Yup, two hours of actual playtime sounds like a pretty fair window to me. Sure, some people are making YT vids where they complete an entire game and return it within 2 hours, but that's not enough to actually matter. For a utility-like phone app something like 30 minutes might be more reasonable, but the same principle applies.
