I think this is a hugely unfair statement. Have you even played Crysis? People always seem to assume it is just a pretty picture, but I found the gameplay very enjoyable as well, and I don't easily appreciate singleplayer shooters. Varied, well paced and a good mix between freedom and linearity.
Does it match with Metro 2033 ? Or at least, Far Cry 3 ? That's a few recent SP FPS games I liked (and in the first place bought).
Ho yeah just so that the younger ones actually know what this is about
