how much is it selling for? I'll probably do like I did for SC and Broodwar and just wait till the hype dies down and get it. It really can be addicting when I first got SC and would play online for hours and a couple times even forgot to eat.
The best thing you can do is alot a certain amount of time to the game, that way you don't burn through it in week and you maintain your social obligations and other aspects of your life. The game does look pretty good though, the ghosts are still strong and have some great upgrade abilities and being able to nuke shit is always a good option to have.
Don't play Koreans at SC you will just get humiliated, it is almost a religion to them. I swear if South Korea had half the weapons in the game they would invade the North just to try the stuff out.
