I am a fairly regular FPS player, though usually online (MW, MW2, BlackOps, Killzone 3). I am super surprised to see so many negative comments about this game. I have only played the single player campaign minimally and only rarely run into any freezes, disconnects, or issues with parties loading. Of 200-ish games I have played there have maybe been 5 instances all told. I find the in-game graphics and experience really enjoyable. Its smooth, and the graphics are gorgeous. I don't know much about the graphic aspect, but it does come in at 1080p (whether that's native or not, I don't know). Are people really having that many issues? Of the 10 or so friends I game with regularly no one is having issues.
On a side note: I am colorblind, so I would love to have the option to change reticle color ala BlkOps. Also the radar map in the bottom left is occasional to light and hard to see, though that may be a colorblind issue again.
