So how does a hand-built (read: no AI, or at least an original concept) compare to what's available and theoretically possible today? If people want a game, they're close to being a prompt away from being able to create and play it - so why would they want a game made by someone else?
Inversely, what is great about seeing a game made by someone else nowadays? It ain't the development because that will be entirely AI soon enough. Game concept? Visuals? I think we're about to reach saturation where everything we produce - that would be considered amazing just a few years ago - will no longer be special and therefore, wanted.
Its going to change, but there's still going to be people out there who appreciate the old forms.
