The mainstream won't care about $70 for more than a little while either before they get used to it and go along with it like they did with paying for online
With regards to $70 games, I don't see it as too much of an issue as I'll just end up waiting for price drops and can just go through my backlog or cheap quality indie games in the mean time. Even Returnal will probably do alright once it gets price drops unless it ends up getting rave reviews
The mainstream doesn't consume games like Era so a $10-$20 increase doesn't change much for them.
