Naïveté. Its not devs that set the price. Publishers do not have your best interests in mind. They will always choose to make more money. They don’t give a fuck about literally anything else.
The prices will never be lower. Purchasing no longer grants ownership. This is why piracy is justified in a lot of cases.
Support devs that respect the community. Steal from those that don’t. Or even better, don’t play games whose publishers treat the community like shit.
