"Popcorn movies" are a big thing, and most of those big investments are these. They're "turn off you brain for two hours and chill" events. A game, even the most chill ones, almost always last much longer and require more engagement. That is the defining trait of the medium. If you can totally turn your brain off then you didn't make a game, you made an expensive movie. Games, for players, are an investment. Movies often aren't.
