Originally I played Wolfenstein 3d as well, there was another game from the same era a lot of people forget about, Blake Stone. There were a few of those 2.5D shooters especially around the time of Doom, it inspired a lot more. Catacomb 3d was a particularly memorable one. Heretic and it's spiritual successor Hexen were also good examples of the early genre.
Quake certainly revolutionized online shooting back in the old dial up era, Quake 3 brought it closer to it's current incarnation and started competitive gaming, Unreal Tournament followed in it's footsteps and later Halo. Duke Nukem 3d, originally 96 the same year as Quake, so early on your timeline, made a huge impact when it was ported to the 64 and other consoles as well. I remember playing that game online as well, it was very popular.
Goldeneye was good, but Perfect Dark is the best the 64 had to offer FPS wise, Goldeneye was great for it's time, it has aged very poorly. When you're talking console shooters, Halo definitely needs a mention, not just because of how popular it is, that game altered the way targeting with an analog stick worked, it single handedly made FPS more popular on console then PC, which was previously the true way to play a shooting game. Sure, the N64 brought console shooters into the equation and many prolific PC shooters like Counterstrike and Battlefield persisted after Halo and still do, but Halo started the shift in development from developing primarily for PC to developing for console.
We could go an list all the FPS games ever made, but one of my personal favorite series was Timesplitters from the PS2 which you briefly mentioned. Head and shoulders above the competition in it's day and still has not been matched in many regards.
Yeah there were definitely some big ones I left out, but that was just a brief timeline.
My personal favorites from some of the older FPS's are Doom III, Quake III, Half Life, Team Fortress, Perfect Dark, and Metroid Prime (my all time fav).
I never had any type of play station, so I didn't really get into timespiltters unfortunately. I never really got into the Halo series either... Don't know why, it just didn't appeal to me as much as some of the other ones.
