3D Gaming Arrives (96-97)
From the interesting cache of weapons available, to Duke's bad ass attitude and the scantily-clad women throughout the game, Duke Nukem 3D was a cliché action movie on steroids and you were in control of it all.
Duke today: After the original Duke 3D was ported to every console and arcade machine imaginable, it received a follow-up side-scroller PC game in 2002. Since then 3D Realms has kept on pushing tidbits of information year after year of a true sequel, the very popular (in vaporware circles anyway) Duke Nukem Forever.
Quake today: The series would continue to revolutionize and open the door for online play, even pro-degree competitions. Most memorable of all sequels Quake III: Arena (1999) met a demand that most FPS fans didn't even realize they had; the desire for excessively fast paced multiplayer action that literally felt like uncontrollable chaos (in a good way). Quake III was so fundamentally based upon the multiplayer experience, that the single-player portion is considered to have simply served as a warm up for the wrist workout that the multiplayer was sure to offer.
Reportedly designed with an RPG style in mind, the game only provided a few key weapons and the rest of your combat was to be waged via powers which improved your abilities throughout the game. Natively a first person shooter, the game settings were capable of being altered to display things from a 3rd person perspective if so you preferred.
The Jedi Knight series today: LucasArts continued to develop games on its FPS franchise with mild success, always exploiting the Star Wars element to offer a unique experience. Nevertheless its been half a decade since the last JK game with most recent releases focusing gameplay on multiplayer action.
