Matt Gilgenbach, an alum of UM as well as the university's game development group Wolverine Soft, has been featured in a guest editorial on Kotaku.
In it, he discusses his soon to be released game Retro/Grade, which is designed to be played with a guitar controller, although a game pad will suffice as well.
In the editorial, he discusses the lack of new game material designed for the guitar controller, which he believes is a major determinant in its gradual decline in popularity over the past few years.
The trailer for Retro/Grade can be found on the game's website and is also below. Though an exact release date hasn't been established, the game is slated to be available "soon."
