I like the structure of Mark's definitions, but I think it wouldn't define products like Neko Atsume, The Beginner's Guide, or Minecraft as video games. I think we generally consider the aforementioned to be video games, so it doesn't make much sense to 100% claim that a video game needs structure or goals. We can start calling them "interactive experiences" or something, sure, but if not I think we should accept that video games are a wide variety of things in our world, and appreciate the variety. Or maybe to be more short, I think it might be good to be a bit less prescriptive of what qualifies as a video game, as we otherwise will blind ourselves to why people enjoy them as entertainment, competition, or self-expression.
