User blog comment:Lancer1289/BioWare gets on the Multiplayer bandwagon/@comment-1655340-20111011072953

From the BioWare statement that DeadDATA linked to below:


 * "It is important to note that the system is entirely optional and just another way players can have control over your game experience – it is still possible to achieve the optimal, complete ending of the game in Mass Effect 3 through single-player alone."
 * "Rest assured that no compromises were made to either of these modes in the development of Mass Effect 3."
 * "Mass Effect 3 is a complete, standalone game that will deliver a satisfying story experience, even if you choose not to try multiplayer. The Mass Effect 3: Galaxy at War system and all of the individual components are meant to complement that amazing game and can be enjoyed on their own or as part of the Galaxy at War experience."
 * "It’s about choice, and allowing players to find their own ways to stay immersed in the Mass Effect universe."
 * "Again, participation in any or all ME3:GaW elements is entirely optional."

So. . ..
