I currently own both games op. Dr who is fun but after 2 games pass im done. Time expander has to be the best toy in pinball. But in my opinion shadow for the win. What a fun game to explorer. Love the call out. Better video mode. Better color dmd. There is a strategy once you play it. Always kept wanting me play. The shadow games are very problematic. But like others have said get a nice cleaned up game with led's its a blast to play
