The Taisen Hot Gimmick mahjong series is coming to the Type X in the form of Taisen Hot Gimmick Mix Party, which will allow the player to choose from all four of the existing THG games. There’s a new multi-ending story mode, and while multiplayer is mentioned, it’s not explicitly stated as being net play. It would be a good move given the technology they have, so perhaps it will be included. The game is planned for a late january release in japanese arcades.
In related news, the Oshioki Box has been released in japan for PC – also a compilation of the first for THG titles, but with additional CG. The first page is moderately worksafe, but clicking thereafter is iffy.
