Wall Street would probably say 15-30,000+. I think the point of the surprise is that actually it’s possible to be massively profitable and have good products without needing massive teams of people. How many mediocre/bad AAA games have teams larger than Valve’s entire staff? More isn’t always better, sometimes it’s just more.
I haven’t read this article, because yeah, I’ve seen this same basic headline over a dozen times in the past week on Lemmy, but I think it’s a testament to what can happen when a private company doesn’t have a lot of shareholders and is run by people who just want the company to run well and be profitable. They don’t have to chase some unsustainable Wall Street expectation of x% growth every quarter.
