Pros: N/A Did not get the chance to experience the game.
Cons: Konami did not make the game supported by anything but on the on-board Harddrive. Individuals with Xbox 360 Arcades will not be able to run the game. There are options to upgrade your HD - DYI seems more appealing since Microsoft charges a heavy price tag for an upgrade.
Summary: OK, so this is not a game, this is a demo at best. Don't spend any money on this. The game itself is good while it lasts, but I just still can't wrap my mind around the plain arrogance of releasing this one as a game, in a box.
