The thing with games compared to regular services is that they start with the bar of rigor a bit higher than normal in all respects. GCs really let you trivially not care about a LOT of things... Until you need to care. Things like where and when you allocate, the memory complexity of a function call, etc. With games you need to care about all that stuff so much sooner. Once you're taking the time to count/track allocations anyway you might as well just do it manually. It just codifies something your thinking about anyway.
