Does Duke Nukem deserve to exist?

Bitmob – It has been over a year since Duke Nukem Forever finally came out, but I only just recently managed to sit down and play through the entire demo without trying to jump out a window…more than three times. During the moments I wasn’t trying to attempt suicide, I began to question why this game was actually released. I don’t mean in the state it is in, though that is a problem as well, but why it was ever released at all.
