A far worse version of that game concept could have been built in Javascript (which you can't even run at speed on consoles because they don't allow JIT), but that's not this game.

Modern "AAA games" cost 100 million dollars or more. Of course if you have an army of developers paid by the hour, maybe iteration speed doesn't matter, maybe the subjective experience of software development doesn't matter. But "AAA gaming" would never produce a game like this in the first place, so it's a moot point.
