You would get better conversation from a cage full of Chimps then you would from the BSN.
I think it's fair to say that's the case on just about any kind of official forum. It has it's uses though.
As for the multi-player mode: The fact that they've opened another separate studio to work on that side of the game basically allays any concerns I had. The system of using MP matches to impact your single player campaign just sounds like a way for players to get the "optimum" ending without having to do every last assignment and just stick to the core story missions. One assumes you can tie this MP score to specific Sheps, otherwise it'll make the final chapter of my loserShep playthrough a bit odd.
Just had an interesting thought...wouldn't it be interesting if references to the MP missions you've completed showed up in the SP game via Galactic News bulletins?
