(O_O) I apologize for the text wall, meant to keep things briefer than that.
The topic did not specify, so I shall list both FPS and TPS.
FPS:
"3D" era:
Doom II is probably the most playable of the Wolfentsein-Doom-clone era. I only played it in 2019, but really enjoyed. It lacks the complex level designs of the Build Engine games, but that was part of the charm to me. It acted (based on the order in which I played such games) as a mid-point between the Wolf-style games (e.g. the Blake stones and the criminally underrated Noah's Ark 3d). I also thought that the addition of the super shotgun in this game made it much easier to get into than the first Doom, helped complete the weapon progression.
Of the Wolf clones (Wolf 3d is required reading, but hard for me to get into) my favorite is probably either Blake Stone: Planet Strike or Rise of the Triad. I've been able to get farther in Planet Strike than Rise of the Triad and that is largely due to the fact that Planet Strike includes a mini map. Rise of the Triad's level design tends to confuse me, but the game is so wacky that I tend to enjoy it anyway.
Of the Build Engine games (namely: Duke 3d, Blood, and Shadow Warrior), it is actually pretty difficult to pick a favorite, but a little bit of background. The first one I played was Duke 3D, but I did not get very far (I thought the levels were confusing), then I played Shadow Warrior and found it immensely enjoyable, I then tried to play Duke again and once again failed to beat it (though I did get through the first episode), then I played through Blood and its X-packs (I also played through the Shadow Warrior X-packs already). Finally, about a year after finishing Blood, I was able to play through every episode of Duke. The reason, I suppose, it took so long was that unlike Blood and Shadow Warrior, I did not find Duke's setting or antagonists that interesting. At any rate, both Shadow Warrior and Blood are first-rate games from their times and I cannot recommend either one enough. Duke is also required reading, but I had great difficulties actually playing through it.
Other honorable mentions from this era would include: Outlaws, Star Wars: Dark Forces, Hexen and Heretic, Strife, and Chex Quest.
Moving into Polygons:
Quake is a great game to be sure but if I had to pick a starting point for me I just love Quake II. It was the first Quake game I was able to get working in full and it is still the one I typically go back to from that era. Unreal is also great but I really just prefer Unreal Tournament (Even as a single player bot fragging fest this game is endlessly enjoyable for me). Quake III is nearly as fun, but that is an important distinction: it is nearly as fun but is just a tick shy of it. The weapons in UT are more fun for the most part and have stronger feed back with more distinctive feel from them. I also like the character design more in UT and even the graphics look slightly more pleasing to me but we are talking about fractions of a point for the most part.
On an in between slot in the time line I would like to throw Soldier of Fortune. The second game is good but the first one is everything good the premise could deliver with gun play slightly more satisfying than Quake II and an inkling of the modern military shooting games of the early 2k that I really miss. This game, however, is gloriously over the top in all the right ways. Go to every hot spot of the 90's and hunt down evil mercenaries who resemble cartoon Nazis more than anything with an arsenal of real and imagined guns with wonderful sound effects and powerful effect on their targets.
Honorable mention of the late 90's would have to be the original Jedi Knight.
2000's:
Another game I love is Return to Castle Wolfenstein. It is not the first WWII shooter of this early 2k era that I played (Medal of Honor Allied Assault preceded it as did the original Call of Duty demo) but it is probably my favorite of them. The right mix of supernatural, SS secret super soldier goofiness and a satisfying amount of gibbing and gun feedback help keep this game in my rotation in spite of its difficulty spikes. I am not a glutton for punishment but this game also does not deter me since everything about it feels good.
If I could I would go on about the game Vietcong except that I never played the full version of the game. The demo was excellent and I played it about as much as the Far Cry, Crysis, Call of Duty 4, and Age of Mythology demo. The only demos I played more were probably the Rise of Nations and Halo Combat Evolved demoes. Instead, I'll go on about arguably my favorite shooter at all which is Delta Force Black Hawk Down. I have played this game to death as a CD and I still do as a GOG game. The game is pretty much everything I wanted from a shooter when I played it (okay, it was not Star Wars, but we'll get there). Your guns are believable and powerful (maybe a little too powerful since bad guys require one round from any of them to down) and you have a mostly realistic and wholly reasonable kit of a knife, a handgun, and a primary small arm (usually a CAR 15 or M16A2) with some extra equipment of a few flash bangs, frag grenades, smoke grenades, and extra equipment of C4, an AT4, or claymores. The claymores are basically useless to me but somebody else could probably have fun with them. This game is not the hardest but it has its moments of extreme cheapness that the only way you can prepare for them is to suffer them once. I do adore this game even still.
Battlefield 2 is another favorite of mine. It felt somewhat revelatory, and I only played it single player. Nowadays I dare not play this game without mods but if the player count could be naturally upgraded to 32 or 64 the need would never have arose. I played this game mod free for nine years with some regularity. Similarly, I play Battlefront every here and again still and with good reason. The original 2004 game on PC in third person is just plain fun. It is a Star Wars battlefield where you can distinguish yourself as one of the grunts for a change. I enjoy killing hordes of storm troopers as Kyle Katarn quite a lot (but if I include every game I like we will never go home) but playing as a storm trooper or a clone trooper or rebel troop is really what I prefer. The battlefields can be hectic and fortunes can change suddenly. Now, after a while you can see the AI patterns but it still can keep you on your toes.
Quake IV is an excellent shooter which combines what was then fairly cutting edge and what was being left behind. You have objectives and little things to immerse you into the game world (mostly the way you interact with computers in game) as well as weapons for just about every number on your keyboard and health and armor packets to be discovered and pilfered. The feedback from these weapons are slightly less satisfying than the ones in Quake II but otherwise I thing it stands up with its fellow Strog slayer. Also, this game still looks great, a quality that will become more common but few games manage to look this good seventeen years later.
The S.T.A.L.K.E.R. and F.E.A.R. games are probably my favorite acronym-named games ever. Both go for creepy atmospheres, but that's pretty much where the similarities end. The former definitely has a more "realistic" approach to the gunplay and inventory management, whereas F.E.A.R. is basically living out your own Hong Kong action movie. Of the two, I would say that S.T.A.L.K.E.R. is probably the more difficult to acquire taste, but is easily one of the most immersive shooters out there, all the games are good, but Call of Pripyat is my favorite.
Honorable mentions include: The Serious Sam games, Unreal Tournament 2004, Timeshift, Far Cry, Crysis, Call of Duty 2 and 3, Medal of Honor: Pacific Assault, and 4, and Resistance: Fall of Man, Call of Duty United Offensive.
2010's:
I'll keep this brief: retro-revival games were very much ascendant in this period and my favorite was Shadow Warrior 2013. The game had great visceral combat, funny dialogue, and a great selection of weapons. A favorite I played around the same time was Metro: Last Light, I realize that some would prefer the original, but I always derived a bit more pleasure from the sequel. I also really enjoyed Titanfall 2. The 2010 Goldeneye on the Wii is an excellent game, if you ask me. (It may seem obvious from the lack of titles, but I thought FPS games were in a bit of a slump in this era.)
I'll keep the above the same, but I somehow forgot to initially include Dusk in the retro revival part. Absolutely brilliant game with a creepy atmosphere, imaginative level design, great enemies, satisfying shooting, fun weapons, amazing soundtrack, and is just so much fun. It is an excellent candidate for best FPS of the previous decade and is the closest of the "old school" games to imitating the feel of those old games (but still does not quite hit it exact).
Honorable mentions: Resistance 3, Killzone 3, Halo Reach, Conduit 2,
2020's:
Only thing I will say is that Halo Infinite is a great game and I like it pretty much up there with the better Halo games.
I will make a separate post about TPS games later, running short on time right now.
