Personally, I strongly disagree with the notion that a game must have a single player experience. Just like I would strongly disagree with anyone who says a game must have a multiplayer experience of some sort. Not only is it perfectly acceptable just to have one or the other, it should be applauded.
Most games just plain do not do both aspects justice. They either have a good single player, and bad/mediocre multiplayer, or vice versa. It would be much better if all devs just really sat down and focused on the experience that they really wanna nail. Not try to have everything just for the sake of ticking more boxes. And yes, there are exceptions, like Halo, that do both parts well, but there's a reason it's called an exception rather than the rule.
And how is a multiplayer game like Titanfall, that you can get potentially hundreds of hours out of, not worth $60? If not, how is a single player only game like Bioshock that gets you maybe 12 hours worth that tag? I find the notion that a multiplayer only game isn't worth what a single player only game is highly absurd.
