Are you familiar with Groove Coaster? If you're an iPhone user, then you most definitely should. Not too many people are aware of Reisuke Ishida's following up to Space Invaders Extreme (which thankfully is fairly recognized; it was one of the iPhone's best games of 2009). But those that have are all madly in love with it (full disclosure: as am I).
And it's making the leap from the small screen to a very big one, the kinds you find in Japan at least. Joystiq reports that Groove Coaster is being adapted into an arcade game.
First of all, the idea of an iOS game being converted to an arcade experience sounds fairly crazy indeed, but Groove Coaster is not the first of its kind. Anyone who has gone into a Dave & Busters here in America will tell you that a blown up version of Fruit Ninja is a fairly common sight. There's even an arcade port of Infinity Blade, but that one is not nearly as common.
Though instead of being a straightforward port, the game will apparently do away with a touchscreen interface and instead employ something called the BOOSTER system, which incorporates the two things you see above. Perhaps it's an Etch-a-Sketch-like interface as Joystiq assumes?
After all, the game's maker, Taito, has promised a "very different control experience" from the original version and music games as a whole.
