The following games represent a many (but not all) of the Xbox 360/PS3 console games with 3D support released in 2011 (and a few holdovers from 2010), and our opinions on how each played in 3D. (Read more on this topic.)
The ruined castle of Ico and the wide-open vistas of Shadow of the Colossus both look great, and the giant monsters at the heart of Shadow--almost sets unto themselves--seem custom-made for this kind of presentation. No real complaints here at all. The God of War: Origins collection, a similar PS3 remake package, is also good, but the PSP source material isn't as well-suited for 3D.
In Arkham City, the wide-open urban vistas benefit greatly from 3D, but the close quarters combat can be uncomfortable, with both the camera and various limbs swinging around violently. The game was much more playable after we turned the 3D intensity slider all the way down (it was set to maximum by default).
