So the kid and the dog you play manages to defeat the evil robot butler him and everyone that helped create the world, Evermore, you're playing in needs to leave or Evermore gets destroyed. They leave and the kid makes it out last with his dog. For some reason he is teleported back to Earth separate from everyone else.
You would think that after fighting dinosaurs, exploring pyramids, firing bazookas at robots, and surviving countless near death experiences would leave a serious impact on a person. Nah, he just chalks up everything to his overactive imagination and goes back to his regular life. Dismissing everything he just went through. Before you're able to start doubting what just happened. That maybe it was all just his imagination. It cuts to the other people that escaped for a bit, where they are all talking about what just happened.
Not like the kid had any character development to begin with, but I think I would have preferred a dumb quick cut to credits over that crap.
