From a wired article today:
So multiplayer will be *required* in order to fully experience the single player game. Sigh.BioWare VP Zeschuk added that multiplayer “makes the whole experience better” for a game like Mass Effect 3. The upcoming RPG will feature an optional cooperative mode called Galaxy at War, in which you can team up with other players to fight off marauding Reapers, earning bonuses and unlocking areas that you’ll be able to access in your single-player campaign.
Also of note in the article,
Then HOW COME IT IS EXACT THAT. (RPS review of Co-op)“Multiplayer … can’t be tacked on,” BioWare co-founder and vice president Greg Zeschuk said
Wired also writes:It’s ultimately a pretty meaningless thing. But where the fun comes from is in realising it’s meant to be. It’s popcorn, alongside the square meal of the single-player game (assuming it’s of the same standard as the previous two – we’ve not played anything of the SP game yet.) It’s not going to be the sort of thing people will be playing long after the game’s been released.
Really? I'm confused then. (Ars Technica review of SWTOR)The Old Republic has no single-player components
edit: Sorry for all the quoting, easiest way I could find to cite all the contradictory information flying around here along with this really scary first quote - if accurate.the game has clearly been designed to include people who want to play alone, and it has options at every point to make that possible. I never felt like the game was hobbled by my decision not to partner with other people
