yup you guys have some of my fav.s in your lists and some I have never played,. good thing for emulation!
Currently I am playing way too much
Team Fortress 2 I have too many hundreds of hours, as the naging stats the game keeps shows me,. . yeah many of the players are sick and annoying ppl,. but at least half the time I find a decent server and get a few good rounds in, The classes really do keep it fresh, when I tire of building turrets, I snipe for a while, then pyro some fire,. etc. I am not able to play as a Medic though as I always just stop healing ppl and start attacking, sad that.
I was a big fan of
Tribes and TF2 almost fills the void,. I am still looking for a structure building/jetpacking type game,. . well I am also trying to build one

I have the design but the math crushes me,.
two that look promising for me are;
Global Agenda and
Brink
My big gripe with current games is all the 'realistic' militerism. yawn,. I am looking for abstract/fantastical/artistic/escapism mostly,. . and that is also what I intend to build.
ICO and SoTC are great,.
REZ was sic!
I enjoyed Zone of the Enders: The 2nd Runner a lot,. gameplay and rendering stye
Half Life (and 2) where very good,.
Mario 64 was a 3D ground breaker,. what I played of the game cube version was nice too,.
Finnal Fantasy Tactics was like a series of advanced chess matches,. with a story,. I liked that a bunch.
I play many of the indie games that come out nowadays on the PC,. always some interesing stuff to be found,. . look
here and
here.
