Totally awesome!!! I am huge Marathon fan and I can still remember playing Marathon 2 over AppleTalk with my old PowerBook 5300cs using a Mini-DIN cable (yes, old AppleTalk networking). And it worked well, too! I hope they have multiplayer arena support in this port of Marathon to the iPad, and I hope they release the full series (Marathon, Marathon 2, and Marathon Infinity). They were all great games...much better than DOOM in my opinion.
