It sucks that this is a p2p networking game. I can understand why though. Server maintenance and costs for a true mmo (not this quasi-WAN game we have now), are pretty high, and without monthly income, subscription fees, I don't think that FD could handle the financials. However, network/computer security in a p2p game like this is bad, to say the least.
So.. solo mode only for me; at least, until FD makes a decision to make this either a solo/group only game or a true mmo game. I'm sorry, but I'm not going to allow complete strangers access to my network.
