Oh come on, that argument that you have to buy the game 'three times' to finish it is !@#$%. There are plenty of games that are split up as episodes and nobody complains about that, they are still long and complete game experiences. (Mass Effect? Halo? Dead Space? GTA4? Gears of War?). The Starcraft 2 campaign is more elaborate than I have ever seen in an RTS. It just so happens that you mostly play with the Terrans. So what?
Oh, but I do agree that the people that run Activision Blizzard (Vivendi) are a bunch of greedy corporate assholes who do not really give a damn about gamers though. But I still buy their games, it sucks.
I have not really played a lot of games against real people so not sure about the placement being good or bad. I thought it was ok in the beta.
Also looking forward to the modding community to do some amazing things with the editor. It can do pretty much anything from what I've seen.
You know what the biggest problem with this game is? Region lock. I bought a US version because I don't like playing with Europeans (they suck at speaking a normal language like English), but now I can't play with some local people. !@#$% biggest oversight I have ever seen, especially for an eSports game that takes itself serious as such.
