Big congrats go out to Vic over at FlatRedBall.com. He's finally gotten the first build of the XNA port of his engine out. I'm proud to admit that I've got a bit of code in that release :-D I helped him start to flesh out the content pipeline for the FRB content files (Scenes, etc.).
It's a great engine, built on a great premise ... and since the FRB XNA package comes with a ready to build project template, getting started couldn't be easier. I can't wait to see what people come up with.
