If multiplayer/co-op and time attacks/challenges/etc are being at least considered then hurray for additional content. You can easily make co-op story based in Oddworld me thinks, it's pretty expansive.

I don't see how multiplayer is at all bad. Even in games that do it poorly, it opens alot more gameplay choices, and styles of play, and it is therefore quite good.

Just because multiplayer has been put into "every" game as you say, doesn't mean it's going to not work in this. I can see how it could work in this with ease.
