TOM is only good if you have a deep collection of machines. If it is one of the few machines that you own you might get bored rather quickly. It is not at all a machine for players. It is more of a collectors item to show off the light shows and artwork and design. Very shallow design and rules. And a wizard mode that is as barebones as you can get.
Once you get comfortable playing TOM enough that you can consistently put up long ball times you'll grow tired of the machine. This isn't like LOTR or MM where long games can still be challenging and filled with variety. Once you master TOM you'll put it up for sale. The game plays the same almost every time once you're skill level is high. Complete Theatre, Midnight, Trunk Multiball, and then try to activate and time each mode out while also trying to get the extra ball lights and awards.
If you only have a handful of machines then TOM is one that won't stay in your collection very long if you play them often. It will take no time at all to learn the rules. And then not that long before you're bored out of your mind of hammering the trunk to reach the shallow wizard mode. For larger collections, in the 20s or more, TOM is a great machine. If you come back to the game every once and a while it will still be an exciting challenge.
