I think a lot of gamers just don't care enough too. I know so many people that buy a game on release, play it for a few hours, and then drop it. Even AAA titles that are actually good.
Steam achievements kinda confirm that as well, there is a fair bit of drop-off on even the most popular games.
Might as well open a Roth IRA and start contributing to an index fund like VTI or VOO.
Long term stable growth and tax beneficial. The earlier you start saving for retirement the better, compound growth is very powerful.
