Masks a New Generation start with very good ideas: to use emotions to describe a fight instead actions (and by the way, actions take their place in the fight). BUT (you were prepared to, right), the mechanical part of the game is his weakness: Masks it's too vague (with regards to villain), so the game it's too open to the personal GM' perceptions and decisions. I would promote the basic idea of Masks, but it would be better if it would be developed with more mechanical details. Of curse, players and game masters who seek very narrative games will love Masks. Even if you don't like it as I don't like it, you could found Masks' ideas interesting using them in other RPG.
