Based on rules alone, I’d say The Hobbit is LOTR 2.0. That game features very unique modes that do not feel repetitive. Each mode is differentiated from the others. It is incredibly deep with the mini wizard modes and There and Back Again. Long ball times on the Hobbit offer the possibility to eventually see the 3 mini wizard modes and There and Back Again.
Pirates is extremely promising with the depth of the code, including the 120 modes and 22 characters to choose from. I really enjoy the character selection, and believe that this is the best overall pin of the bunch. Although the code is incredibly deep, at this point, the modes do not feel unique. That is perhaps due to the lack of an ideal licensing agreement. The game has a lot of multiballs, and collecting super jackpots is important for later in the game. Another great code set, but lacks the overall character of The Hobbit.
I’ve played WOZ on location several times, but have not experienced much of the code due to quick drains. The crystal ball modes are great, however.
