This depends on what MTL they use. GPT 4 is great even without any editing, if someone could integrate it with textractor or app then most people would be able to comfortably play any game easily. And edited GPT 4 (if you set it up the right way) is pretty much the same as official translations, except it wouldn't have any additional editing like most official games that often change the original jokes, etc. Unfortunately, most makers of MTL patches still use GPT 3.5, deepl, google, etc, which are way, way worse, because they aren't ready to pay even a mere 200$ for a much better translation, lmao. And some MTLs are made by prompt or something because they aren't even google-level.
