Always been Terran! I played StarCraft the day it came out and really loved Terran. I just kept it up with SC2. I've been playing random in team games for the last year or so, so I can play the other races a bit. I think if I ever make my goal MMR for Terran I may play Zerg for a while.
Terran, same as when I played brood wars! I have had fun playing Zerg too. I'm a scrub gold league in 1v1. I mostly play 2v2 with my wife, it's the only video game we both enjoy together.
