Sewer Levels Explained and Dissed

I am intrigued by things digital, but somehow never got into gaming, yet anyway.  However, it appears that gamers have gone heavily into sewer scenes in their games (I recall writing  on Ninja Turtles some time back) and of late, there has been some backlash to these "sewer levels" (as they are called).

First, let's define what we are talking about here:

Now for the anti-sewer level rant:

Be sure to click on the entertaining comments below the Readers' Digest ad for "27 Foods You Should Never Buy Again," and its accompanying photo of cheese—hard cheese, say like Asiago or Ragusano or a Grana Padano. (Which, if you click on the link in the last paragraph of the article called "15-tonne lump of fat and filth" actually, kinda makes sense.) Not that I have anything against cheese in moderation. I just hope this link is still there when you get to this article and that it hasn't been replaced by an ad more tailored to your interests in case it does not happen to be dissing cheese.

I know, I am straying far from Los Osos. But frankly, the sewer news around here has been rather thin of late. A good thing, I think. We really ought to expand our horizons beyond the conveyance of bodily wastes.
