Yes, you can setup servers, but you are going to have to find out if certain ports are blocked. What I would do is setup Apache to listen in on ports 80, 8000, and 12345 and see if any of them work. RoadRunner blocks alot of incoming stuff -- ports 80,23,21,81,8080,8081.
So most servers on my end MUST have an alternate port. That should be the ONLY limitation -- blocked ports. If you cant figure one out, try using a slight variation of your favorite games' server port. AMy help out.
