Always strive to learn something useful. --Sophocles

It was definitely different from Doom and Quake, both in content (the first level in the adult theater) and in the kind of weapons and tools available to do things with. (It was also the first game where the rating system setting actually changed things.) I never finished that much pay the first few shareware levels, so maybe at some nostalgic point, I'll go back and actually play it.
