What if you hire voice actors for each of the characters? And level designers? And animators? At what point does it stop being a solo project? Only when outside investors get involved? Or does it only stop being "solo" if those investors demand board seats? Or can it _still_ be considered "solo" even then?
Yes, if you're also doing game design.
> Is coming up with the game design and hiring programmers "developing" the game?
Yes, so is using LLMs to do the programming.
