As long as we're on the topic of Borderlands...
I bought this on App store as soon as it arrived and have been playing it for weeks now. I'm at level 24 and it's been a great ride, I'm not even halfway through the single player missions yet. The game has such a polished feel to it. Thank you @ Feral for not using Cider and making it Mac-native.
But I'm wondering, since I bought it through App store, and I sync all my apps to both of my Macs, is there any problem with running this game multiplayer on my two Macs with my "single" license of the game?
I tried it on a LAN (not over the Internet, i.e. I wasn't using GameSpy). It didn't work; neither Mac game sees the other one on the LAN. I didn't pursue it much further, because I don't really have anyone else to play it with... I just was curious to try it.
So, is the license blocking me, or (more likely) a firewall issue? I've heard that I need to open up some ports when playing multiplayer, even on a LAN. I'm using the default firewall settings, whatever the Mac defaults to. I've read various PC boards and nobody seems to agree on what ports are used, so they just turn their firewall off entirely... I don't want to do that.
