the only reason i'd want the game is as a portable chessboard, so the inclusion of hot-seating is a necessity for me. i'm getting conflicting information from Pushsquare's review page, though.
the review states: "Sorely missing, however, is standard multiplayer. There's no local 'pass the system about' hot-seating, nor ad-hoc, nor straightforward online. Instead there's message play, in which you and a friend can send moves to each other via PlayStation Network, with up to eight games running simultaneously."
but then a comment at the bottom of the review says " I don't know why reviewers keep saying there was no local multiplayer option. There is. Just change your opponent in an exhibition match to human. It's sad that the game gets bad reviews because of this misconception."
