The novelty of 3D is wearing off slowly, which is a good thing. There's a divergence now into more specialised branches of 3D, such as photorealism (have you seen Crysis 3? By Jove!), stylism (Borderlands), and "mainstream" (Starcraft 2, Diablo, Warhammer franchise, etc, all much of a muchness when it comes to distinguishable technology). Fortunately this divergence is allowing 2D graphics to become accepted as it is now apparent there is room for style beyond ever more photorealistic graphics.
Or a nice combi, like Fez. 2D puzzle platformer but the world can be rotated 90 degrees. I like those kind of 2D games that actually use the third dimension as a gameplay element only.
Crysis 3 looks spectacular but at the same time it bores me to tears really. The realistic look makes it so it doesn't speak to my imagination anymore. Its really not for me, I'd rather play Borderlands 2
The cell shaded cartoony look provides me with the entertainment I seek in a game. Not to mention nice coop play of course, a highly underrated feature that can really elevate an FPS game.
Mission: Derailment is a success by the way
