I'm... not sure. I've tried it once and made it to the victory in one try. The reasons probably are that I'm familiar with the mechanics and was lucky with drop, but it felt like it's not as difficult as RF2 anyway. The game pace is higher though, and there are more of everything - enemies, skills etc, so it's harder to balance I guess. Can't say I really love the new level-up system with talent levels also. RF2 felt more... relaxed even if more difficult.
