This is my main concern about the game. With tech that moves this quickly, you have to understand that game companies who are established are living on the very edge of that debt.
Like starfield for example. Who knows how old it’s code is from the start of its development. It’s why Bethesda games break frequently and crash often. When you develop games on a 8-10 year cycle, think of how many hardware generations that is. 3 to 4 right? So when you’re talking about building an engine, then running it and building a game, then supporting it, all over the coarse of 15-20 years of coding? It’s a giant mess to program and there’s no way in hell it can be optimized properly.
Not to mention the massive task of upgrading the game as new hardware and new engine features arrive.
