The tcket alone is between $10 and $20, add any snacks… But it was just an example. Think of anything you do for entertainment (that you actually pay for), and the cost per hour. Games are pretty cheap. Like do you have any streaming services? I do, but I play games more than I watch tv, so games come out cheaper.
All in all, people complain about the cost, but usually get hundreds of hours of entertainment out of a single game.

$20 for a two hour movie ($10 per hour) sure

$70 for a game ($7 per hour if you only play 10 hours) no way.

Though I am a fan of pirate first, pay when they fix the bugs. The low quality of games at release and the whole seemingly 10 year pre-release cycle sucks.
