(No real spoilers in the following): Done--sort of. Before the ending where the % counter comes up, I got 83% of the items (including 69 missiles & 12 energy parts) in about 17 hrs. Then, when the counter came up, I was up to 93%. I'm now at like 98% or 99%. In essence, the game is about beaten. Some really nice surprises at the end, and also some anti-climatic things. Regardless, despite this game's imperfections, it's easily between an 87 and 93 out of 100 for a review score depending on how picky you get. I'm leaning toward 93% just because of what it did accomplish and how fun and engaging it was. The biggest success of this game, in my opinion, is the relaunch of Metroid in 3D beyond the conventions of the admirable but ran-its-course Prime saga. The biggest shortcoming is the overall lack of meaningful, fresh innovation in power-ups and thematic areas. (Fusion suffered from the same problem, and I wonder if that's a result of both of them being "relaunches" trying to reestablish the Metroid name. I hope so. Over three games, the Prime series went a long way in innovating the areas, but outside of the fantastic Boost Ball and maybe the interesting Thermal and Command Visors, there wasn't a ton meaningfully new in the Prime series, either).
