Metroid Prime 2 - I got everything, I think. One thing that makes this game much harder than the original is the fact you can't tell if you're missing anything too well. You'd see a "?????" on missing Logbook entries in Metroid Prime, but in MP2 you don't get any prompt other than the meters (and when they're close to the end, it's hard to tell).

However, I think I'm good to go. I attempted the final boss a couple of times, and I keep losing to Emperor Ing's walking form.
