Fable 3 has finally hit our PCs! Months after the Xbox 360 release and apparently rebuilt just for us. I've been ill these past few days, but I'm back, and just in time to play it.
The game itself so far is pretty fun, not the best RPG I've ever played but enjoyable. Then came the attempt at playing co-op.
My router is horrible at connecting to other people, especially if they're behind a router too, so I had tons of trouble as I expected.
The two main problems were not being on a static IP and having a weapons DLC that my co-op partner didn't have.
Your DLC is different: If you have the free weapons DLC, or your friend gets an error saying they can't join because of a DLC, you need to get rid of it. You can do that pretty simply by opening Games for Windows Live outside of Fable 3 and just deleting the content in the downloads section, it'll also disable any other DLC connected to it. You won't be able to load any of your single player games that you played using the DLCs until you reinstall it though, pretty annoying.
Network connection failure: If you're having network issues and either are you behind a router, it's a little more complicated. First off you want to get the obvious things out of the way, firewalls on your computer and router. If that doesn't work, you can do two things.
First: Make sure you're running a static IP off your router connection, you can find guides for that purpose
here. This actually worked for us, and we could play without even playing with port forwarding.
Secondly: You can try opening the Xbox 360 ports, though you need to setup the static IP before that, you can find how to do that on most routers
here.
Good luck setting up, guys.
