@[email protected] Ah, Duke Nukem 3D. This is probably one of the most unique FPS games I've ever played. The interactive environments in particular were awesome and it's kind of a shame we barely see stuff like this in modern shooters.
Funny story, my dad once told me that he bought Duke Nukem as a teenager, but refunded the game since he thought it was a rip-off of DOOM. After playing the game in its entirety, I must say he heavily missed out on an incredible experience.
