The old FPS games were much more like the bullet-hell shooter games, in 3D and without the spaceships, than like modern shooters. I think Serious Sam was the last time I played that style of shooter, and while I've enjoyed tons of modern FPS games, they feel very different. The latest Doom games (the ones after Doom 3, confusingly titled Doom and the upcoming Doom Eternal) do a great job combining that old-school shooter gameplay with more modern elements. I highly recommend them!
