I GOT STARCRAFT 2 BETA MUAHAHAHAHHAHAHAA
I really like the game although I never played Starcraft Original,although I'v played lots of Warcraft III. I'm still playing Practice League
So far these are my thoughts on the race.
Zerg
Really love the whole concept. Larvas mutating into the units is awesome. Spam Zergs and evolve them into Baneling and self-destruct them at ennemy bases muahaha

This race has a lot of synergy also. I also managed to get a decent army of Mutalisk and Ultralisk because of the "gold crystal" mine. Oh and the Nydus something is really useful,was able to transfer/teleport all my units so fast.
ProtossNot bad,also love the concept. I don't really like their units and was suprised to see the iconic "Zealot" as their "Noob Tier" unit

I do like that they can "Summon" building with only one worker just like Undeads in Warcraft III.Sadly never managed to be able to build Dark Templars.
TerransReally really nice concept. Moving your bases around ftw? Plus upgrading the main base into a Command thingy(the one with the MULE) is really useful. I love the Reaper unit with the jetpacks

Oh and Ghost + Nuke research ftw?!

Also love the Hellions,great to scout around. Must importantly though,
