By The Pokemon Company. Regionlocked. Not personally interested but it’s always nice to see apps from major companies popping up on Android Market.
Interestingly there is a second app, “ポケモン映画プレイバック・ザ・ヒストリ(Pokemon Movie Playback The History)”:https://market.android.com/details?id=jp.co.pokemon.movie, which, while not a game, is not region-locked.
Actually now I’m starting to wonder if I should have bought an Android tablet while I was in Japan, since I could still link it to the US account and theoretically purchase Japanese apps. But uh … yeah.
