Sensory processing disorder associated with autism is exactly what came to my mind because it’s exactly what I deal with. I usually shut down instead of melting down, but kids playing at anything past a barely-audible level is extremely difficult for me. Other attention-grabbing noises are also difficult, like dogs barking, car doors closing, people yelling, etc., and other stimuli cause me to shut down too, like dogs jumping/breathing on me (basically everything about dogs, unfortunately) or someone touching the back of my head/neck.
It took a lot of research into how my sensory processing reacts to different things, and I still struggle frequently, but I’m a father now and most days I’m very happy about it. I have noise canceling headphones for when I get overwhelmed, and I keep a clicky mechanical keyboard switch and barrette in my pocket to fiddle with, which helps a lot.
OP, I can obviously only speak from my own experiences, but I think dissecting what exactly causes these sudden emotional bursts and finding sensory distraction or blocking techniques to dampen them might work for you too. Headphones are a godsend.
Edit: Definitely seek a professional opinion (if possible for you) and look into misophonia, especially if specific sounds are your only issue. I just wanted to provide my perspective because for me the exact same issue the original post describes was part of a broader thing that needed addressing.
There’s something called “Brook’s Law” that basically observes that a software project which onboards more developers in order to catch up will fall further behind. I hope they’re careful about how they allocate new developers or they’ll end up doing a year of onboarding, rewriting core code, and have no meaningful updates for 6-12 months. I know they have the resources to spare, and that scenario worked out okay for Valheim, but I hope the game doesn’t lose momentum because they overhire or don’t allocate enough senior devs to continue feature development while they catch the new devs up to speed.
Edit to add: I don’t think it actually matters in this instance if they don’t have a large player base by the time the game is feature complete. They don’t have continuous revenue streams like a live service game, so hiring more devs is ultimately just about making sure they have enough talent to make good on their early access promises. The company could probably dissolve tomorrow and all the staff could live the rest of their lives in luxury never working again. It’d be a dick move, but they already sold an insane number of copies.
