Do with this information what you will.
I will use it to teach Oaks on how to properly bake bread!
MTL + AI art, lol I can already see the future of the next generation of lazy devs.
On the upside, they (as whole, the works) are improving. What started with RPG Maker (and perhaps whatever 3D girl for porn) did transition to renpy, grammarly and Blender/Koikatsu. Now we can see a vast improvement incoming Auto-TL and Auto-Art. Basic Coding can also be done/checked with automation/by AI but this one is less ripe.
Remember, one year ago AI Art and ChatGPT just became a topic.
For now, most 'professionals' (those who want to and can provide quality) do use renpy and Koikatsu until AI Art becomes consistent, flexible and affordable (i.e viable, same applies to translation). There is basically but one who 'professionally' AI-translates the works here and tweaks the engine (or script) and it sure is something to be thankful for. Since it is based on commissions which requires some demand while the engine is available to the public.
Neither programmers, writers or artists will go out of business if they are actually good at what they do since it requires a professional's competence to prompt, tweak, edit and check a work to make it flawless if not outstanding. Now I really don't recommend writers to let AI produce their 'basis'. Grammarly already serves as editor while proper prompt-ing should provide references and suggestions.
Especially German RPG Maker Games are/were infamous for the dedication many teenagers had (born around '85-'90, it took off with RPGM 2k rather than 95), while producing utter trash one after another. In terms of writing and, well... somehow it become popular to construct maps that consist solely out of a spiral pathways. One creator especially refused to improve/grow up, after making 10 lengthy entries into a series over 10 years. German Quality? Sure, there are some many German RPGM gems but well, they are sensible enough to not advertise (translate) their failures.
