Call them 'retro,' call them 'classic,' or call them 'just plain great,' first-person shooters from the 90's like DOOM, Quake, Unreal, and Duke Nukem 3D have inspired countless game developers to pursue their dream job of making videogames.

Some game developers have been so inspired by their favourite shooters that they've taken the time to craft their own FPS games as homages to the greats, with modern conveniences included for modern audiences, of course.
