I met a few like that Ry, especially on ANZAC Day. I remember back in the early 00's we did one up at Bowraville and there was this guy with a fake ID and a moth eaten suit telling us that he was CIA and lived up on the hill at the house with "all of the communication dishes and aerials".
He tried to get on the mini bus with us for the service up at the cemetary and the local coppers locked him up.
You could see it in his eyes though. He carried himself like Trumps personal secret service agent. Talking into his collar.. no doubt saying that the eagle had landed.
It allows the developer to get into the feedback loop earlier, and allows the community to guide what they are doing both right and wrong during development. Not post-release.
It's a double edged sword, but the days of "It's done when it's done" are slowly disappearing in favour of more modern approaches to the development cycle.
PUBG was incredibly buggy early on, but the fixes came hard and fast. Without launching the game and having that wide ranging and immediate feedback, many of those bugs would likely skill exist in the beta.
It's popularity speaks for itself. It's not all doom and gloom.
