Think about it this way: You spend 10+€ to watch 2 hour movie. That is 5€ a hour. If you spend 90€ into HOI4 and only play 90 hours of it, it still is better value than movies. Only if you play less than 18 hours movies are worth more. Of course movies are still different so you still would want to go to movies, but since you are talking about justification of spending money, my point is valid.
