Battlefield 1942 and Battlefield Vietnam... those were our LAN party games back in the day. I didn't get into Rainbow 6. A lot of my gaming was single player stuff though - Max Payne, the GTA series up to San Andreas, FEAR, Vampire, Borderlands I and II, Halo, so many good games.
My gaming career started on the Mac platform in the late 90's and I stuck with that until about 2003 or so when I built a PC with a 900MHz AMD Duron in it. That got me by for a while, upgraded to an Athlon 1400, still have that machine. I built a few more after that and kinda lost interest in games probably around 2013ish... after I had about 200 hours into Borderlands 2, I was just kinda burned out and my computer (that HP Phenom based deal above) was just barely squeaking by for that game.
I probably won't get back into games much, too many other hobbies to pursue but I still have a dozen or so old computers set up in the basement so I can take a trip into nostalgia land anytime I want to.
