I used to work in a large FB/Mobile game studio (one of the largest) and was on a team that launched a certain FB flash-based game. It was a project that was on "crunch" from beginning to launch (about 6-9 months). Literally 3 days before launch we found a severe flaw in our client-server communication layer that didn't do what we needed (this was almost a decade ago, I no longer remember what exactly the issue was). I spent an entire day heads down rewriting the whole client-server communication architecture that day. I've been in non-game, software dev jobs after that company, and can't imagine something like this happening in any other company/industry, even in aggressive scrappy startups. Duct tape and hot glue are pretty much the norms in game industry. Like you said, I also wouldn't trade that experience for anything else, but I am also never going to get back to it.
