I confess, I purchased this title (on PC). I haven't purchased a Call of Duty since Modern Warfare (original), and that's one of the reasons I bought this. I also wanted a fulfilling single player game that I could get through in a weekend and wasn't going to take 40+ hours which I just don't have at the moment (I'm sorry Outer Worlds, you look great though).
Modern Warfare (original) single player was fantastic (imho). Interesting story and characters, so when this came out - and it wasn't a remaster-of-the-remaster, I thought I'd get it.
While the game is well produced, it falls far short of its spiritual predecessor. I got through the entire campaign on Veteran difficulty in ~6 hours. The story was lacklustre and the only character I can recall is Captain Price and that's mainly because he was in the original 'Modern Warfare'.
The story is just bad with a terrible ending that involves (*spoiler*): the death of one of your squad for absolutely no reason. You've cleared the entire facility of bad guys and yet he announces over the com in the ending cut-scene he's not going to make it ... not only does it make no sense - the logical equivalent of deliberately sacrificing yourself to demolish a derelict building - no one on your team bats an eyelid, it's also too short and the missions are uninteresting.
Compared to the heart thumping tempo of the original this is a poor imitation and a good reason Activision won't be seeing any further purchases of the series from me.
