Wow a new Sega game on Dreamcast I never thought Sega would make new games on DC. I think it was easy to port it on DC since it's a Puzzle game and that it will be release on above all platform. Anyway it's a really good news
This game is being released on the neo-geo MVS hardware in the arcades later i belive. It was going to be released on the naomi, but they changed it to MVS. I think there only releasing this on the DC because they already had the code writen for the Naomi. The Neo version looks diferent because of the MVS being weaker hardware.
