Right. Americans play without any strategy at all; no Americans have made any competitive Pokemon websites or done any kind of metagame analysis or played in any tournaments or anything.
This is a silly topic. You can't reduce something like this to "brawn vs. brains", as if where someone lives on the planet dictates how they play in the game. Besides, there hasn't ever even been a true communication between American and Japanese players on any kind of large scale.
There isn't any kind of magic strategy that we're all missing, and I'd be willing to bet that if there is an online competitive scene in Japan, their style of play is remarkably similar to ours, simply because after some years of playing, there aren't many things that we could have possibly overlooked, and what works "here" is going to work "there" as well. It's the same game with the same mechanics in both countries, with intelligent people on both sides looking for what works.
I hope this doesn't turn in to an "lol americantz r dum" topic.
