Hello, myself and my friend have started saving up for a trip to Japan next year. We're both students majoring in Game Design and we grew up on games from Japan. We'd LOVE to see a tour centered around gaming in Japan.
A few examples of things to do and see would be Akihibara and Harajuku, Japanese gaming arcades (like these: http://www.cnngo.com/tokyo/play/4-best-tokyo-arcades-424517 just for a list of location ideas, the article itself is kind of strange o.O), a game/anime museum (Ghibli Museum maybe?), perhaps a video game convention in Japan like the Tokyo Game Show: http://expo.nikkeibp.co.jp/tgs/2009/en/
And also there would be the more traditional tourist attractions like Tokyo Tower, temples, parks, hot springs, tea gardens, and nightlife (Roppongi!!)
Since anime and games go hand in hand there could be events centered around both!
I think it would be very popular! I know for sure at least 2 people will be booked for that one haha!
