There is not a catch all machine that everyone is going to love, but in my area, beginners seem to be most attracted to games with interactive "toys". Toys like: the castle in Medieval Madness, ship in Star Trek, t-rex in Jurassic Park, goal in World Cup Soccer, Kenny in South Park, Sparky in Metallica, etc. I think toys also appeal to more advanced players, but it has to have more depth then just a good toy. They tend to care more about how a game shoots and how balanced a game is. Spamming a toy shot over and over is okay for a beginner, but your advanced player will tire of that rather quickly. Of the games I listed most have wide appeal. I feel like the exception is South Park, which is a great earner with beginners, but is rather dull for advanced players.
