Video games have costed roughly the same since like the 90s, so really it is not that bad that they went up slightly with inflation. I don't like it but it is an unavoidable reality. 60$ in the 90s is worth more than 70$ in 2020
I will also say that I have already seen some 70€ games here in Europe several years ago. They were not common and if you looked for other retailers you could usually find them at the more usual 60€, but they existed
Of course, here is where I also mention that the 60/70€ price is including taxes, which I don't think is the case with US pricings? (then again 1€ is like 1.1 USD so it balances out I suppose)
