The game will be split into three separate products, based around the terran, zerg and protoss campaigns respectively. The first is called Starcraft II: Wings of Liberty, the second will be called StarCraft II: Heart of the Swarm and the third will be called StarCraft II: Legacy of the Void. So if by Starcraft 2 you mean Starcraft 2: Wings of Liberty then yes only terran but there will be three game products for the zerg and protoss campaigns.
It is only for Terran, but other campagins will come out later
it is way longer and way more detailed
No because you're only playing as kerrigan working w/ zerg.
For now, the campaign has only Terran and (a small number of) Protoss missions. In "Heart of the Swarm" there will be Zerg missions.
If you mean the three races, they are Terran, Zerg, and Protoss.
Welll I beat the story mode and I only got to be Terran and Protoss.... i only wanted to play Zerg too....
it depends on what you are against, but the Thor and thew Battle Cruiser are both pretty strong
Well, it DID come out. But only in the Campaign. The medic was probably considered too advantageous in early game and took it out of the scenarios and put it into the campaign.
My favorite Race in Starcraft was the protoss, as they have good health and good damage and medium mobility. Only drawback is that their units build slower and are expensive to produce. Starcraft TWO i cannot be sure, as they are upgrading all of the races. But im probably goona stick with my usual rankings. (Protoss first, Zerg second, terran last.)
The original isn't at all required for SCII Though I'd recommend it for the storyline
I would guess that he is in his 40's, though I have heard that he is exactly 33 during the Starcraft 2 campaign.
It is highly suggested that you go and check The Shokz Guide (link below). It is the complete Starcraft 2 Mastery Guide. The Starcraft 2 Guide is an in-depth guide teaching you how to master the Terran, Protoss, and Zerg. Great Guide! You can become the commander of an army, and control your units (for example: where to go, which enemy unit they should attack, etc.).
