I don't think you can delete posts. So instead i'll just edit this.
Let's change the topic...
What backstories/class did you guys choose for your Shepard?
I chose Spacer, War Hero, and was Soldier for all 3 games. In the first, I made a little backstory about why he has a scar (the one that goes down your eye), like a piece of shrapnel hit him.
All except one Shep have been Earthborn and either War Heroes or Ruthless. Nevertheless all, ALL my Shepards have been Renegades (usual Paragon:Renegade ratio has been around 2:5)
War Hero or Ruthless my Sheps always maintain that she was just "doing her job" and doesn't care if ten die to save hundreds. "I did what I had to do" is what my Sheps say every time someone questions her Renegade actions.
I could argue that it holds more playability than GoW horde mode. It's repetition is staggering in comparison to ME3's MP. And at the present moment, I see little reason for them to endorse single player dlc when they have said they have no intentions to add new endings. All they're going to do is add cutscenes and/or codexes to the end and call it the "extended cut" (source, BSN-Mass Effect 3 News and announcements). I can see throwing out support for the MP being the better option in this regard.
I can also sympathise with people disliking it for the forced better ending, but only to the extent of the galactic readiness level modifier. I managed to complete the game with a little more than 9000 Resources and only 1700 of that was from multiplayer (I figure it was because I messed up some of the options and recieved some losses).

Edit: on an unrelated note, maybe it's just because I'm tired, but I cannot read the red text above for the life of me.
Never played Gears of War and indeed I never will.
I just don't see the point in Multiplayer. It's so primitive. It has no goal. Then I suppose I'm just not one of those who gain self-confidence from high scores. My N7 is only about 90, I've seen people with 1500 and I am worried what those people do with their free time.
