It would be nice if they just went portal style and made an elaborate tutorial disguised as a campaign. That would make a whole lot more sense for this series I would think.
I don't play many shooters whatsoever, but if you're not going to go all out, I wouldn't even bother with a single player. Just hearing the words "quicktime events" tells me that this was a bit phoned in.
And of course, trying to copy Call of Duty is just ridiculous. You can just imagine how those marketing meetings go; a giant boardroom of people who think in numbers and check-marks instead of quality or originality. I would prefer that Battlefield just focuses on what it does best. Hammering out the best quality in your own unique direction is the only way they'll get those numbers they so desire.
