Full complex app, forget about it. It’s not going to work.
Concrete functions or small parts of the program (or maybe a very small project? 50/50 chance. Depending on the complexity.
For instance I benchmark several LLMs last month, asking them to build a worldle clone for the terminal. Some of them were able to spite the full program in a completely working state.
For anything larger or more complex I haven’t had any luck. And LLM are mostly used for references and ideas.
For mods the better approach would probably be that each game community host their own mod portal. No single point of failure.
