alot of people have been talking about the amount of blood in starcraft2. apparently in korea they have strict censorship laws about violence in games (GTA is illegal), this is probably the biggest reason for blizzard not making the game overly violent. heres a news article on korean gaming http://www.gamedaily.com/articles/_a/why-south-korea-dominates-the-online/20070611102509990001
They could also just remove the blood in asian versions >_> Btw, people are people chopped in half in sc2, thats kind of violent
Given the popularity of the starcraft series in Korea they won't place a ban on it. GTA is "teaching" people to kill and steal in real life like settings. SC2 is too fictional and they know that those blood and guts and violence in SC2 don't mean that much
I'm Korean, and every time I play a game called Counter Strike, or Half-Life, and I somehow get a head shot and see a spray of blood that so happens to spray on a wall, my mom or dad give me a weird look. I mean, Korean parents expect their kids to be the next Donald Trump, and to see you with a gun in your hands killing even people online kinda, to be frank, scares the hell outta them. Not to mention anything they think will get in the way of going to college or get a good job...
