I've been watching a playthrough of Duke Nukem Forever (because I don't want to play the actual game). Firstly, it looks really, really fun. Not smart, not something that I would play through multiple times, even if I did play it - it doesn't compare to Fallout 3 in the least - but fun, in the same way that watching a mindless action movie can be fun. Secondly, picking up feces from the toilet is entirely optional, and reflects upon the reviewer as well as the game. One of the major selling points of the game was that everything can be interacted with, so what did you expect?
