10. Quake for PC
I'm giving Quake the number ten position mainly due to the fact that it was the first 3D game I seriously invested time in. As far as gameplay goes it's fairly identical to any FPS of the day (back when Doom and Doom II were kings). Where it shines is it's use of 3D graphics and overall creepiness. It seriously scared the crap out of me countless times. It was also fun to play around with the console commands to change gravity and how enemies act. If you ask me, without Id softwares numerous game offerings we wouldn't be enjoying the FPS's of today.
