Everyone knows that the best way to learn something is to keep practicing.  This goes with Starcraft, as well!  I know that when I first started playing SC1, I wanted to master every race, so I would always pick Random.  I later figured that I usually did better whenever I stuck with one race and learned all the ins-and-outs of their strategies.  After I mastered the skills of said race, I moved on to the next, to eventually DESTROY ALL LIFE!!! HAHAHA

Well, when I played War3, I still did the whole Random thing.  It seemed more feasible on War3 because, to me, War3 is like a Starcraft that gives the players a pacifier, bottle, and diapers.  The game was so... accommodating.  I sure hope SC2 isn't this way.

Well, for SC2, I'm going to try out all the races first, then I want to learn Terran!

They look cooler, and they rocked in SC1 if you used them well.

I'm most proficient with the Zerg in SC1 so they'll probably what I'll have a look at first, but considering the first part of the single player campaigne will be all Terran they might be what I attempt to "master" first.

I found the single player campaignes in SC1 the best (but by no means the quickest) wat to learn a new race's pros and cons.

To be honest though I really don't know. I don't really have a stand-out "favourite" race at the moment, they're all really cool. I guess it'll mostly depend more on what my friends go and how similiar the races play out in comparison to SC1.

I'm a Toss player so def Toss will be the first race I try in the game...

Gotta get down that Proxy Pylon Warp-Gate rush

Next will probably be Terran, then Zerg(the race with the least amount of polish as the others)

I use Terran a lot in SC1. I'm going to try to master Terran first then I'll probably move on to Protoss then Zerg.
