As a long time fan of the Shock games (System Shock 1-2 as well as Bioshock 1-2) this game in general has annoyed me, despite the fact that I'm REALLY looking forward to it. It's just not a Shock game. Where's the dead world you have to explore feeling alone and desperate as you find audio logs that gradually allow you to piece together the back story? An amazing and still effective set-up to this day, a set-up so effect that even System Shock 1, a horribly outdated game, is still worth looking at. That's just a minor annoyance that shouldn't effect the rest of you.
What worries me is how streamlined it actually looks. Shock games always have been unique, at least until games like Doom 3 came along and copied them, but despite the amazing world this just looks like another shooter when you watch the gameplay, and this box art and the whole "must-have shooter of 2013" also worries me further. It's still going to be an amazing game I'm sure, but I don't want Shock of Duty, I want Bioshock! Ah well, hopefully it's just the gameplay we've been shown. Either way it'll be amazing, and it's not like I'm the kind of person who completely shuns shooters for being shooters, heck I got Black Ops II Hardened Edition. (as much as I love and respect games like Bioshock, alot of times I just want to relax and have fun, and I personally feel Call of Duty does that better then any other game. If it pisses you off all the time like many people you obviously aren't going in with the same attitude I am, and don't yell at me for liking a game you don't please, the fact that I have to put in this long parenthesized comment just to try and keep the CoD haters away alone should put alot of the internet to shame.)
