I enjoyed the direction Prime 2 went in. The level design has been improved from Prime 1. The Morph Ball puzzles in Sanctuary Fortress were a big highlight for me. The Sky Temple Key search was more intuitive than the Artifact hunt. Exploring Dark Aether at first is tense and frightening, until you get enough upgrades to feel immensely powerful, and thus you overcome your fear. Why do people think this is the black sheep of the series? Genuinely a lot more interesting to play than most Nintendo titles. Only issue I have is how sluggish Samus controls. She moves like a pregnant cow, I wish she was faster.
