Actually the Dreamcast charges are the equivalent to 1200 yen, which as of purchasing my last Hunter's License on the Dreamcast, my card was charged $10.07. Not bad for 90 days of play. Hopefully that pay structure will continue on the other versions of the game.
Count me in as one of many who is waiting on the BBA to be released in October. Offline multiplayer is keeping me entertained while I wait. BTW, in case you didn't know, you can battle and do challenge mode in offline multiplayer.
