Just thought I'd mention, as I did in the PS4 thread, for anybody picking up an Xbone. Battlefield 4, for many people, is an unplayable mess across all platforms so far. They have disabled features, sent out patches, and sacrificed virgins, yet the game is still quite unstable. I believe that Conquest/64-player mode is still disabled for the PS4 version, and that was one of the biggest bullet-points for next-gen. Of course, EA and MS have their "historic partnership", so maybe it'll work fine for the Xbone(which would cause a shitstorm of epic proportions; EA worst company in America three years in a row?).
If you decide to pick it up anyway, the game is excellent when it is working(multiplayer, at least). Just be prepared for frequent crashing, and various other bugs.
