Online, I'm on a Rogue Spear (an R6 sequel) kick at the moment...my 56k won't let me play anything better. I would be addicted to BF1942 online if I had cable.
Nobody but me liked Ghost Recon (another R6 title). I liked the big maps and the fact that you had to plan your way out of situations more than just blast your way through.
All the Doom/Halflife stuff was fun, but to this day, my favorite shooter was Outlaws
It was this old-West themed game with cruddy graphics, but the gameplay for the 100 or so of us who played it online was fabulous. Lots of stupid but fun mods like zero-gravity and one where all the character skins were saguaro cactus. Nothing like spending a whole game dressed as a cactus, shooting at other cactus in a field of cactus.
Yeah.
