The funny thing about MMOs is that while they’re very obviously video games, they’re not really in the same wheelhouse as single-player games. They’re different in terms of time commitment and the social structure around them. Heck, they’re even different than multiplayer games like fighting games; there are similar aspects, but they’re still not the same thing. On some level, they feel like they’re different from other video games.
But they are video games. So that’s a worthwhile question: Are MMOs in the same category as other video games for you? Do you count five hours in Guild Wars 2 as being functionally the same as five hours spent playing NieR: Automata? Or do you find they occupy a different mental space in your head, as if they’re more of a related but slightly different breed from other video games?
