So, I find this news to actually be kind of hilarious.
Here, Titanfall was looking to be the one and only Xbox One exclusive title that was actually good, that actually had the potential to move units and sell Xbones all by itself... And it just pissed that all down the drain. I don't know, maybe something will change between now and when the Xbone launches in a few months, but my personal experience working at a game store is that online-multiplayer-only console games do not sell. At least, not for very long. We have massive piles of copies of Socom Confrontation, MAG, Shadowrun and Warhawk that we can not get rid of for longer than a day. People come in, want to buy them, and then return them, frequently mere hours later, after realizing that the game has no offline mode for them. We could not move these games if we were giving them away. Because we HAVE. We've given out copies of some of these games away for free, and people still don't want it.
Mind you, I'm certain Titanfall will sell better than all those games. For starters, it'll likely be higher quality than all of them, so that'll help, but the number of people who don't have a good enough internet connection to be able to play, or just aren't interested in multiplayer (which, for FPS games especially, has a bad reputation for attracting obnoxious 12 year olds) is not to be underestimated. Combined with the still lackluster enthusiasm for the Xbone in general as well as its higher price tag, and I suddenly see a lot of anticipation and desire for this game dropping off.
And what makes this so ironic to me is that it's being done by Respawn, aka, the guys who made the two GOOD Call of Duty games. I don't actually have any friends who like playing CoD multiplayer. Hell, as a whole, most of my friends detest the entire CoD franchise, BUT, they all make exceptions for Modern Warfare 1 and 2's single player campaign.
