Damn that’s crazy. I thought TF2 was one of those games you can’t play anymore, because they had people abusing bugs to crash servers or whatever. But it got fixed and you can genuinely play it like… 7+ years after release? Titanfall 2 also used to use the “we need you to buy mtx to keep the servers open” strategy, lmao. I also think the artists behind TF and TF2 are leading passion for the project and a few have just made more art in the same vein in their free time, as well as more collabs and promotions after release. But again this is years ago.
