As I recall, Return to Castle Wolfenstein was purely scripted, had terrible textures, had the classic no-aim-down-sight, had a character that was capable of holding more than 2 guns, had a flaky and reused storyline at best, had no gunplay mechanics besides a little recoil (damn that sten gun), and enemies progressively become bullet sponges, oh and on the hardmode enemies were bigger sponges and you had to strafe everywhere in order to complete it. Also the final boss was a joke, and the Uber Soldat boss was the real end boss in terms of difficulty.
And yet it is one of the greatest FPS's in existence. I personally loved it, I loved Wolfenstein 3D, I loved the Wolfenstein from 2009 (I got it in a store for 99p a year after it came out because a bunch of retarded, self entitled reviewers decided that because it was merely a wolfenstein game with added mechanics of crystals and upgrades, it was a bad game), and I am going to love the new Wolfenstein. Because, it is just a Wolfenstein game.
I'm sure the game devs will desperately try to make it different to all other FPS's by adding some nonsensicle gunplay etc, but that's the beauty of games like Wolfenstein and Doom. You're just a guy who can carry 27 guns, half a dozen of which are bigger than him. Oh and you get to steal chicken dinner from nazis. It doesn't need fancy mechanics or gunplay to be good. It's Wolfenstein for Christ's sake. Nobody takes it seriously, they just buy it to have fun.
