I didn't really know how to phrase the title, but anyway, my question is this:

With games like Demon's Souls and Journey doing a sort of multiplayer that is really a part of the singleplayer (or maybe it's more accurate to say that the singleplayer and the multiplayer modes are one and the same), where the only control you have is that you can go offline to stop people from joining, do we need a term to seperate this kind of online play from "normal" multiplayer and cooperative play?

I'm hoping we will see more games do this kind of multiplayer, so I think it would clear up a lot of confusion with a good term for it.

co-operative integrated single-player experience

I would deem it a subgenre of the MMO, at least in terms of how to define the multiplayer itself

Lets call it BOB

It is kind of like that, but it doesn't really do it justice. MMOs are big, persistent worlds that are shared by all players.

With these games, you get a much more directed multiplayer than MMOs offer (for now at least), not to mention you can play offline.

Maybe we should call it möbius-player games, because they are both multiplayer and singleplayer games at the same time.

Combo-player maybe?

I think your thinking to much about this.

So far the poll shows 100% support for it, so I'm not totally alone.

EDIT: It did at the time of writing at least.

I was just thinking about how best to tell someone about a game like Journey. Sure, it's a coop game, but if I tell them it's a coop game and say they can't play with their friends, they'll think it's a sucky game, when it's really a great game (I'm in the beta, it's awesome)!

how about MSPE

Multi Single Player Experience

Since you are still experiencing the single player but with Multiple players also experiencing the single player

Ambient or indirect multi-player experience
As opposed to competitive or co-operative multi-player
