Until everyone switches to the vastly overpowered A.I.

Well, I've seen many of those pass by in the past few weeks actually. And the biggest issue with those is ... you see them coming a mile away.
I haven't actually played one of them yet, but ... YES, I agree ... the art looks pretty good at a glance.
BUT ... (most) each game looks pretty much the same, which is why I say you can see them coming a mile away. As if there's only 1 art-style the AI knows.
And mostly all those games were from different, first-timers. No doubt the game is a throwaway too.
Art is the bottleneck in both games. Unless you're really lucky and find different artists who can draw in a very similar way ( or you don't care if the game has different artstyles). Drawing and colouring usually requires more time than writing and building the scene, and even more if you have a lot of variations.
In that case the collab with Scarlett Ann should alleviate that to some degree, as they've basically got an extra 'art design team' to do the arts for them.
