They are playing online- each playing on their own computer. Shawn is playing on his computer in his office at the front of the house. AJ is playing on the computer in the kitchen, in the back of the house. "How technologically advanced!", you may say. Not so much.
They have spent the last half hour screaming across the house at each other things like: "Where are you?", "I'm by the stone wall!" and "There is some gold over here, do you want it?"
They might as well be playing with dixie cups and string at this point.
