I never meant small in terms of profits, I only ever meant in terms of development resources, that’s what generative AI will impact. The most humble games can become huge hits, see: Stardew Valley. With a better cost proposition, we might just see those psychological surreal point-and-click adventure games.
Also do mind that Final Fantasy XV: Pocket Edition isn’t a gacha, it’s a scaled down port of the game of the same name that’s divided into ten chapters; the first one’s free, but the other nine will cost you. Meanwhile, Final Fantasy VII: Ever Crisis, a free-to-play port of Final Fantasy VII too will be episodic, but it will have a gacha for weapons and costumes.
