Even thought people (normies) tend to attack gamers a lot, there's no way to deny that thanks to gamers and gaming in general, computer hardware advanced at an accelerated rate thanks to the mass adoption and the game devs always pushing for better graphics, psychs and other hardware intensive features that forced hardware companies like Nvidia, ATI/AMD accelerate their development process and start competing to be the number #1 company.
I bet something similar will be able to happen, my favorite imagination scenario would be an MMORPG where the crypto is mined every time a monster is killed and then you can either use the currency you earn with NPCs to buy stuff and burn it in the process or trade it with players for items or real money and create a digital economy, there would be a lot of math needed to prevent crazy inflation by people just farming mobs to get it, but it still would be pretty cool to try it out!
Us gamers are always looking for the bleeding edge of tech to get the best experiences possible so we will probably help mass adoption too!
