Your note on the divergent meta strategies that develop in geographical (server) regions, resonates with me. I remember in the days of Brood War playing on the Asian or European server with my trained-in-America skills usually resulted in quick matches. My strategy always seemed to be more macro heavy, so all I'd need to do is survive the micro-heavy early game harassment and by mid game I could just A-move to victory.
It's amazing how similar it is to divergent evolution in the biological sense. You have almost all the same factors at play.
And to your note about "trained-in-America" skills, it's a really amazing feeling to have those interactions in any game, isn't it? It's a sense both of pride and identity in your own training as well as appreciation of the different styles of the game. A little bit tribal but very exciting!
