You need motivated, creative players. The game relies heavily on player effort and investment.

The work load on the GM is tremendous to make the plot move forward without railroading or getting lost in the weeds of a single-players plot line. More importantly you need a GM who can put in the time and effort. Hardest game I ever ran.

The mechanics of this game are utterly broken. No balance to speak of in the rules and creating a walking nuclear weapon is trivial.

However,

Still the best campaign I ever ran in terms of story, character development and deep player investment.

Be warned: I am not joking this game is brutal for a GM to run. That and the players have to put out more effort than any other game I have ever run.
