I wouldn't get too excited ... all he is doing is graphics right now ... hasn't even looked at a game engine ... he told me that sometime this year he is going to start a kickstarter drive for funding for the game ... honestly it looks a lot more like a graphic design school project than anything else ... all that effort into design one arena
Hope it works out ... the more the merrier but until someone comes out with a game engine that is even close to what Andreas has then it's all just pretty pictures
edit: his last post was 2/12 so not sure how quickly it is moving
