I bought bo4 because some friends were playing it. Did not really expect to be enjoying it that much and would probably end up just playing zombies, but I was completely wrong. The multiplayer is still fast paced but without the elements of flying which really ruined it for me in the past few games. I have not spend much time in the BR mode but it seems really solid and fun.
so if you think 60 euros/usd is much, then wait for it to be in a sale, but it's worth picking up! (:
