I just got a MB this weekend and have to say I was not really expecting the similarity I feel to playing my Tron. They are obviously pretty different games, but what I find really similar is how there are numerous "modes" which you can start (blinking lights on the Tron ladder - monster faces on MB). Getting the first "tier" of these modes are fairly easy and get you to what I guess I would consider the first mini-wizard mode.
Finishing each mode (solid ladder lights on Tron and lit musical instruments on MB) is obviously more of a challenge and will get you to the main wizard mode.
So far, MB seems like the easier game but it is certainly fun.
I was just curious if that similarity has been discussed before. I quick forum search revealed nothing.
