If game prices were tied to inflation, they'd be $80USD now. $60 dollars in 2006 money is about $80 now, and I seem to remember games being that price back then.
Now, the fact it's 80 euro changes everything. That's like 95 bucks in USD. Games in the 90s could reach that level of expensiveness on SNES, but we're past the days of cartridges upping the production cost when blu-rays exist now.
It really just seems they're trying to make next-gen feel "premium" through expensive game prices. And when game profits are through the roof because of anti-consumer models like microtransactions, it's a shame that they're pushing the profit margins even further. I'd happily take more expensive games if that meant no microtransactions, but I doubt that's realistic.
