Quoted from Lermods:
I guess the difference with mando is because the shots are so close, if you brick it, you’ve lost control and there’s a good chance it winds up in the outlanes. Forget going for the targets on the right and left. With Metallica and twd, there’s more chance to nudge and regain control. I find mando to be brutal, frustrating and sometimes not so fun. But, when you do have that great game, it is rewarding.
Hard games seem to last longer at my house, so it isn't a bad thing. Considering how many reviews come from "I played it twice on route and it sucked" it's not surprising to be a little lower on the top 100.
If I want to have a good game on Mando, I have to catch and trap the ball. If I try to let the shots flow and just string them together, I hit the posts (and there are so many posts) and straight down the outlane.
The mini play field takes up a significant amount of real estate causing the fan to be a little crowded. The shots are so close to the flippers. The left ramp is super steep and it takes a clean shot to get up there.
So, yes, Mando is a "harder" game than most. Just one more game, I know I can crush it this time!
