That's just personal taste... I buy games solely for the multiplayer because it takes longer to complete and it has endless possibilities, thanks to mods. I completed the campaign on the hardest difficulty within 9 hours... if I pay €60 for a game, I intend to play it more than 9 hours

I really need a multiplayer.
I agree with you that games should be made for PC and then ported to the consoles, but what you're saying about the pricing... I believe the PC games still cost about the same, but the console games have gotten cheaper.
