This is a *fascinating* concept for games studies - "quotes" of a game that don't just show you a clip of gameplay, but actually let you take control and try it out. It trims the ROM down to only what's needed to run the quote, so this might even pass a fair dealing/fair use test in court if it came down to it - just like quoting a passage of text, or a clip of a movie.
