The thread about games that are similar to
Duke Nukem 3D made me think about the following. There's a secret area in the first level of the shareware episode of
Shadow Warrior, which is a red-lit room with a couch, a TV (that shows someone getting flogged for some reason; maybe a pop reference but I didn't get it) and a cache of weapons. I've always thought of this secret as a "sort of" reference to the rather hard-to-find secret in E1M1 in
Duke Nukem 3D, where there's a rather similar red-lit room with a couch, a TV and a stash of weapons. This similarity was even greater in the leaked beta of
Shadow Warrior, where this secret room is swapped with the starting room, so that you have to jump on a car to reach the secret room (somewhat similar to having to jump on the palm tree in
Duke).
I have very little doubt that these similarities are a simple coincidence, however such a reference is quite different from directly referencing the Duke character (BTW, there's also another level in
Shadow Warrior where Lo Wang comments a huge explosion with "Looks like Duke Nukem!"). So I've been wondering if there exist other suchlike references that point not to Duke himself but to some element of the game - a similar obstacle, level design, puzzle, secret area etc.? The game references should not necessarily be
Duke Nukem 3D, of course
