The examples are in the video I linked, as I said, if you don't bother to watch it then I'm not sure what to tell you. As I said for games I don't know and won't presume to search up some random vibe coded game if I don't have personal experience with how LLMs handle games, but for web development, the sites I've made and seen made look pretty good.

Edit: I found examples [0] of games too with generated assets as well. These are all one shot so I imagine with more prompting you can get a decent game all without coding anything yourself.
