You can't really be in the 'know' of a game if you don't play it. Theory and practice are 2 different things, as I always tell me fellow engineers. You can have a perfect blueprint on paper and then when the thing is built it fails for reasons that you didn't anticipate.
That being said, stick with SC2. No game since has been anywhere near as good as that one. SCV is a close second, but still not as good. Why? Because fighting games went down the toilet when arcades died. They tested games for balance by letting people play them, and then releasing a console version with balance changes. It's the reason why SC2 has, and always will have, better balance than any game since.
But hey I just realized that I broke one of the websites 'sacred' rules. I'm not allowed to bash any SC game. Woopsie daisy.
