If they can't sustain this they should shut down their business. Xbox hasn't had a 10m+ selling game in more than a decade and is still hanging around and spending $80B and doubling down on producing games.The budget alone are just the games though. That’s not factoring in marketing costs or licensing fees. Another Thing is that last of us didn’t sell fast enough. Took several years and now they’re trying to rerelease it on ps5. They can’t sustain this. Developers themselves are saying some of the things I’m saying here as well.
"Not sustainable": Developers across the industry react to The Last of Us Part 2's $220 million budget
As budgets soar, devs break down what that meanswww.gamesradar.com
Based on the leaks we know TLoU Part 2 still sold a few million more units than GoT. Even if doesn't end up selling more than the original TLoU it still sold really well (a lot of the sales of the original game were the remaster including heavy discounted and bundled).
Not sustainable was also being said about BG3 earlier this year. Turns out what isn't sustainable are the likes of Redfall, Starfield and Hi-Fi Rush that sell like shit.
