I can’t find it now but there was a pretty good blog post on HN(it was marketing a product to solve this problem, but felt legit). That basically divided game development into four stages. Stage 1 is you can just one shot vibe code the boiler plate, stage 2 is you can like more specifically vibe code certain features, then I forget specifically, but like you have to have pretty deep subject matter expertise to handle the networking code.
