I vibe-produced a website for an (earnest?) pastiche of Final Fantasy games (i.e., for a game that does not, and probably never will, exist). I noticed that Nano Banana could generate reasonable facsimiles of Square Enix's promotional render style and ran with it. Next up: faking some gameplay or a few shots from an FMV-style cutscene.
