DX 11 is found in all versions of Windows 7. No need for ultimate.

I'm aware of that. It's just that in this situation, I have the option to either get Ultimate at a discounted price or XP.

Which OS is better for gaming? Apparently Ultimate is geared more for business, but I have the urge to utilize DX11.

Hard to say since they're both pretty different. History demands that I favor SC2.

Marines are actually good starting units because of their range alone. Also, there're two reasons for expansions: To increase resource intake and as a safety net for when your resources at your main diminish. As for good units against Protoss and Zerg, it really depends on what they're building. Marauders are great against roaches and stalkers. Vikings decimate colossi. Hellions incinerate zerglings. Scout for info and take advantage of it.

Like Creative said. Study your replays, play a ton of games, try different strategies and see what works.

You can have up to 4v4 I believe - maybe even 5v5. But yes, you can be on a team with your friends and fill the other team(s) with AI.

No, I don't believe there's a 5v5 option.

Probably at least a 9. Doesn't really matter. I've been playing since Brood War, and I already played the beta. Definitely will love it.

Yep, the original StarCraft. The core of the sequel is relatively similar, which is why I'll love it.

Isn't that step back?

Not a chance. Since OoT, people's expectations are unreasonably high and will probably never be met.

I'll settle for a 'good'. No 9's or 8's. Just good.
