HOW? I DEMAND AN ANSWER! It was by far the most impressive game visually at the Gamecube's launch.
Well, that's your opinion. Well, it might be your opinion. Its impossible to tell when/if you are serious (are you ever serious) about something/anything. Luigi's Mansion and Wave Race both had much better graphics, IMO.
I've played the arcade Monkey Ball. It used to be at the Gameworks in Michigan. It is a Naomi game for sure. It was originally meant to be a DC release after that, but it ended up being one of the many games that were shoved onto other platforms mid-development (Orta, Gun Valkyrie, VF4, etc) after Sega took the bribe and killed the DC.
