To clarify, this means that the first ever appearance of the character must be originally in a videogame rather than the character simply appearing in a videogame? Or would the iteration of Patrick Star from Spongebob: Battle for Bikini Bottom work? Or the Linux Penguin from Tux Racer?

Your first assertion is correct, although be aware that I made an exception for Geralt who's originally from a book. A character simply appearing in a game is not enough. No Patrick, no Goku, no Sam and Max. In fact, even original characters from licensed games for non-game properties are not eligible, like the main character from Star Wars Fallen Order, for instance.
