Requires thought, strategy, and practice to master online. Players work their way through the ranks whilst besting online peers in the community. A great Starcraft player is best described as someone with the mind of a chess master and an ungodly amount of dexterity. Absolutely the best game you can buy, for it teaches how to manage time wisely as well.
My son loves this game. While there is a little violence, it is cartoonish and is usually seen from far away in a "bird's eye view". It requires strategy, logic, patience and maturity--not like many other video games that cater to those with short attention spans.
I was skeptical about this game, namely from the Battle.Net revamp which left out many key features from the first game, but it turns out that I love it!
A note bingomanatee about the Korean thing: There is no cross-server play (as of now) so if you bought the game in the US, you'll only play people in the US. There is also a nice matchmaking system that puts you against people of your own skill (roughly, of course).
The zerg are a pretty scary bunch, reminiscent of "Alien" monsters; a bit freaky even with the top-down perspective. One possible concern, which parents should be aware of, is that the entire country of South Korea plays this game with feral intensity, including sponsoring compounds where kids (they start as kids anyway) play day and night - so intensely that their hands move like hummingbirds, too fast to be caught on camera. This means that the competition can be VERY intense! This can be quite demoralizing for kids who just wander into the multiplayer environment. Making sure that your kids play with other kids to ramp up will be better for their self esteem. I'd not be especially concerned about the sexuality - the female of concern (Kerrigan) is kind of a cross between X-men's "Mistique" and a gargoyle.
avoid the 1 player campaign and you will be safe if you are older
while i am 28 years old and very careful with what i watch and play, i don't feel like all teenagers can say the same.
there is violence, swearing, and even a bit of suggestively dressed girls in this game that you should know about.
this isn't a kids game.
it is set up to be addicting as well, so you should really be careful with this game... though, i must say it is the best game i've ever played :) you just need to know a head of time what you're getting into, and stay away from the 1 player campaign if you want to avoid most of the a fore mentioned, possibly offensive material.
Definitely the SC2 game is aimed to active minds; the more you can achieve in "mind cycles" (mining, construction, production, scout, combat) the more you are able to develop a high paced multitasking sense.
And this is not end here, you must be creative at the same time, the limited information about your rival challenges you to wonder about what to do, when to do and how to do.
I think the very competitive nature in the game can discourage to some kids with security issues, in that sense, the game can be useful to challenge the kids to deal with the insecurities and develop a commitment with put your best effort and improve constantly. SC2 is a mix from theory, exercise and constant practice.
As bonus points, the community in SC2 is huge, and we hope to grown even bigger: live events, broadcast events, local tournaments, replays, commentators, analysis, discussion, competition.
