btw...
TriOviz
?
You know, the type of 3d that relies on glasses with red/blue lenses, that can be used on any TV? Rad Racer had something like that, but it never worked.
Anaglyph 3d/stereoscopic 3d is the generic term, but TriOviz is the specific stereoscopic technology they're using these days. (I'm not sure if the colors make a difference, but the lenses are pink and green instead of red and blue.)
Game of the Year Edition Arkham Asylum added that, and gives you a few sets of 3d glasses to go with it.
