To all the doubters and idiots: http://www.wegame.com/watch/Starcraft_2_Trilogy_Announcement/
Now watch it and weep, because I'll be getting all 3 campaigns.
Really, some people buy Mass Effect, a disappointing RPG that is only 10-15h and has NO multiplayer, and think it's a great game.
Some people buy Halo 3, which has a crappy singleplayer and dumbed down multiplayer, and think it's a great game. Etc...
Just look at people what Blizzard fans decided in the video, 99% of them preferred to have 3 seperate EPIC campaigns.
