Free? Why is it free? I don't see any iAds on that screenshot. Why would they do this for free?
Bungie released the Marathon series as open source software just before MS bought them out (presumably so MS wouldn't own it). Bungie is completely irrelevant to this story... other than the tremendous amount of credit they deserve for originally making the series.
Being Bungie sanctioned, as the article states, is completely inconsequential to the development and release. This would be like saying the Firefox browser is sanctioned by Netscape (I know, I know, Mozilla was... but that was a long time ago).
Daniel Blezek deserves credit for bringing Marathon to the iPad, the article serves to discredit his work by indicating that Bungie has anything to do with this at all (besides blogging about it). The fact that there is no mention at all of Aleph One, the engine that will no doubt be used, and depriving credit to all it's developers is downright rude of MR.
