The Ending
In the End we see Tillman driving in a car with his Daughter in the back, his Wife next to him, and at some point he looks at the tattoo on his arm.
Earlier there was a scene of him thinking about exactly that scene, and at the time it appeared to be a memory.
So is that supposed to mean that the entire film was actually just another game? That "Society" and "Slayers" were just two games within the larger unnamed game?
