I've only played the single player campaign, but yeah, the graphics on pc surprised me. Looks good with everything maxed out. Graphics wise it can hold it's own against bf4 to me.
The people I have talked to said it was a terrible PC port. No field of view slider, poor optimization, huge hard drive 50 gig install for mediocre graphics. I have read lots of complaints about the single player campaign being bad. Multiplayer, the game itself is built on a good core shooter so it's always going to be entertaining on some level if you enjoy post CoD games, but it doesn't seem to add much to warrant a new game over just playing previous versions. Having not played it myself, my impressions from reading other peoples reviews are that if you just can't get enough CoD, then this will give you more maps, new weapons and tweaked perks, but if you were hoping for some sort of major innovation or reason to play this over past versions, then you won't be missing much by skipping this one.
Ive been gaming since I was 10 in 81. Im impressed by all the new stuff. I bought ghost and like it prrsonally. The peek and slide feature is pretty cool. I guess im gonna keep playing games and listen to rap till they put dirt on my grave
