Something that came to me regarding what is considered literature?

I don't think you can consider videogames as literature, because it isn't written.
It's visual. So it could be visual art, but not literature.

What about text based adventure games???

That and the majority of text based RPGs out there.

Haha, I forgot about them, but that's true. I guess you could consider them as literature: but then you could consider multiple choice adventure stories as games, too.
You could say, "No, it's a book, it's literature!", but I could easily retort, "Well, you're interacting with a story on a screen, so it's a videogame."
That's why I prefer putting videogames in visual arts.
