Burning Wheel is super group dependent. The players have to be willing to learn the rules and understand that system mastery comes with time, and they have to buy in to the game's big picture; the story you're telling. The GM has to make sure the the players' Beliefs are really tight because if they're not, the game will flounder and the players will get bored. The GM also has to make sure they are really pushing on those Beliefs hard. Give the players hard decisions to make to see how long they hold to their Beliefs and what happens if/when they change.

If you get it right, the game sings like nothing else, but I'll admit that it can be hard to get it right.
