When Black and White came out, I knew so much about the games that my first run through felt like my second time. I had a plan, I knew the gym leaders, I knew what all the Pokemon looked like and their types. This was due to the fact that they were released in Japan six months before their North American release. All the info I wanted was out there from people who could translate Japanese. However, X and Y symbolize a major shift in the Pokemon marketing campaign. October 12 isn't just the release date for North America, it is the official global release date. This means that the world will only be behind Japan for a few hours (depending on release times in stores). This has radically changed how American consumers receive Pokemon updates and info leaks. We have as much information as the Japanese consumers, which isn't that much considering the size of these games. How exciting is that? For the first time since I played Red and Blue, I will not have significant prior knowledge of these games.
It may be silly to put emphasis on the unknown of a game, there is always the off chance that it's bad. But I think it has added to my experience, and I haven't even played the demo that has been making the rounds at conventions. I want to recapture some of the mystery and excitement of my first Pokemon experience, who wouldn't?
