5: Multiplayer
Running with the mantra that everything sells better with multiplayer added, Mass Effect 3 is the first entry into the best selling series of formerly single player games that suddenly adds an online component. I never care for those, and I admit this is a very personal reason, but I play Mass Effect as a single player game. And that part usually suffers from having the developer split resources to do multiplayer. Also I resent the “everything must have multiplayer”so for me it’s a matter of principle.
