Different people, different opinions Peach. You can't go and say that everyone buys it for the Single player or even 99% because they don't. I said that popularity is higher in single player then multiplayer, but people, still, buy it, for, the, multiplayer.
No one buys an IP's first attempt at multiplayer for the multiplayer alone, because it's nothing but a gamble.
A minority deserves to be recognized. Even if it's less then 40% or even 30% but to say 1% buy it for multi is a ridiculous assumption.
Most buy it for Single Player.
Some buy it for Multiplayer.
Some buy it for Both. <<< I fall into this category, I'm 50/50 on both side.
And btw, at my Gamestop the guy I talked to there (whom usually give me good feedback on games) told me that the Multiplayer is definitely a good part of the game. It's all opinion based.
