I always regret never having played the original Fallouts as I know they were considered legendary. So yeah, FO3 was my first.
BTW, I just had my first "Confirmed Bachelor" dialog with the guy behind the counter at the NCR outpost. I gave him the old "So what's your name?" line and one thing lead to another. He finally explained regretfully that, you know, he would and all but people here out west just don't understand "special friendships" like they do back east. I called him a spineless pussy and stormed out. Bah, he wasn't even that good looking.
