Hmm I don't think we have the right to complain about a game that won't make it outside of Japan. Sure we're all Castlevania fans, but this game was made for the Japanese market. As far as I know, Pachislot is a cultural thing in Japan. It doesn't exist in the US or Europe, or at least not in that form. So why are you guys so pissed at a game that won't ever make it outside of Japan? If anything the Japanese fans should be the ones pissed, since they could get a complete CV game, but instead they're just getting a Pachislot game.
And who knows maybe those games are fun to play. If it ever comes out on iPhone for example I think it might be interesting to try it out.
