This year the Tokyo Game Market moved to a new location. A better location, with more space, which mean more games :) The stalls almost doubled in number, and there was even an auction & bazaar where people sold their second hand games. There were a lot of foreign companies there this year: Playdek, AEG, Gemblo, Happy Baobab...
It was a lot of fun. If you are ever in Tokyo or Osaka, and you really like board games I would highly recommend you visit the Tokyo Game Market.
