Who has StarCraft?

you gotta play the game a lot, that way you get a feel of the different races, and you then can realize which race you play best with and which one you detest the most. Upfront, I can't tell you whos the best to play with... because I may be good one the race you may be worst with, as in my cousin, he plays best with zergs, but I love marines and protoss. Anyways, play offline in custom games and practice, otherwise you'll never know realize the bits of info that really matter.

you should first play offline so you can see which race you are better in and then you go online. you should also learn how to micro and learn unit controls and resource management. hotkeys are really important too. memorize most, if not all hotkeys and the most important thing is practice, practice, practice. if you lose, watch replays and learn from them
