Own both, and at first they seemed similar to me as well but they're really not, and I can't put my finger on why they feel similar now that I'm analyzing it. I guess because they both feature a lot of ramp-to-inlane flow, but looking at both playfields side by side, the placement and travel of most shots isn't all that similar. The themes and scoring are really quite different as well. They're both going to last a long time for me, two of my favorites.
