DI is a joy to play, I've own mine for a year now and I enjoy playing it more than any other game.
It flows like no other game, the modes and scoring system are designed for that flow, it's smooth, fluid, an impressive achievement in Pinball design IMO.
I haven't seen all of it yet, there's some good surprises, the quantum theater is a toy like no other and I do enjoy waiving my hand in front of the camera to scratch a ticket.
Definitely underrated and top of my personal list.
