Well I'll be insane, so may as well decree educational courses in playing games in school akin to getting to watch classic films when you get lucky. Probably the best way to promote what you like coming out is for as many people to learn how to play them and get a taste for them, even if many don't care for, say, Super Metroid you'd also have way more people who have played it, know how to play a game like that, and may want more at least occasionally.
If I'm going to be more reasonably sane: tight as fuck regulation on how F2P is handled. The closer it is to gambling and scaming people of money the more it's going to be controlled until outright banned, and stuff like stamina meters can fuck off. Maybe also subsidize "core game" development, and when that's healthy subsidize innovative new titles.
