--- Comment #87 from Fleck Fleck@Rullz.lv --- No true! Windows has loopback device, it's just hidden and not visible by default, like many other things in Windows! You can even set up Windows to show loopback device in Network Connections as adapter (google for exact steps how to do it)!
About game - I don't think it's address problem, I think it's the problem with that function, returning wrong, empty or bad address! You have to think from other side - for example - Age of Empires III gets addresses just fine!

I think the info here about the /etc/hosts is relevant: http://appdb.winehq.org/objectManager. php?sClass=version&iId=9180&iTestingId=34524
The game itself warns about having more than one address, it seems to bind to the first one, if it isn't the correct one it will not work. In linux, maybe the 127.* is the first one, which isn't going to work. Windows doesn't have that kind of address, so the first one should always be the first on a real adapter (eth* or wlan* kind of devices)
