Amazing how in this age of online internet gaming, the focus and priority is given NOT to quality multiplayer games, but instead to the ability to tell each other how amazing the single player versions are.
What is wrong with you people? You sound like 12 year old fanboys.
No, I just want a good singleplayer game. Mass Effect started out as a singleplayer franchise, that's where the main draw has always been, and that's where resources should be dedicated. There's plenty of good MP-oriented franchises like Battlefield, CoD, WoW, StarCraft and Age of Empires.
There's not many truly great singleplayer series right now. Mass Effect is one of them, so the singleplayer is what I'm focused on. If ME4 has bad singleplayer, the series will die on its ass, unless the multiplayer is something absolutely groundbreaking. Weak multiplayer, on the other hand, won't undermine a pretty good singleplayer experience.
