Gaming definitely costs more, but it also offers a lot more for the price. A lot of $60 games have 100's of hours of content. Which is like 50+ movies worth of content.
$8 each for a movie theater ticket would make it more expensive than a $300 console + $60 game.

Not to mention games at least come down in price a lot more readily than movies. Disney movies seem to stay at $20 for a DVD, whereas I can buy The Last of Us right now for $17. And the latter is a 10+ hour experience.

But yes, overall gaming being more accessible and not just by price is always a good thing.
