Matt goes down a very simple list of reasons why you should play this game.

IMPORTERS:
Despite being only sold in Japan, anyone that wishes to import on 360 or PS3 in any region will happy to know that the game is completely region free and can be played on any system. It’s even been localized in English, French, Italian and Spanish! It’s costly at 100$ but considering Sega as no real firm plans to release this is NA as of yet, it’s totally worth it!
