I finished the game right before bed last night!
(I'm not going to lie; along with doing church stuff, I was playing a lot this weekend which kind of cut into my VGMaps.com updating time. Sorry about that! >_<)
Anyway, I wanted to get 100% of the items (made easier with the satellites that reveal the locations of all of the items in most areas) and 100% of the scans, but unfortunately I missed four Space Pirate enemy scans...stupidly, one of those four was the scan of Meta-Ridley, since I replayed that battle since it was kind of cool but forgot to (re)scan him. >_< I finished at 15:36, for once having a better time than my brother in a Metroid game!
Be aware that once you finish the game, it will ask you to save. You will need to save to unlock the remaining bonuses, but doing so will revert your save file to the very beginning. If you want to keep a save file at the end, copy your save to another slot before you go to the last area (you'll know what it is and when you can go there, as you will be told within the game that you cannot return if you go there; at least they extend you that courtesy.
Anyway, the final area and final bosses were neat, but they and most bosses are a little on the easy side, especially compared to previous Prime games' bosses. Though maybe the challenge is in Hypermode Difficulty which I will replay it at later (much later, and it won't cut into VGMaps.com updating time, I promise!) since replays keep the scans you got the previous time(s) around so I should be able to get 100% of the scans now that I know what to look for (yay, GameFAQs!). And maybe by then there will be an in-depth FAQ for all the secret Friend Vouchers.
ENDING SPOILER (kinda)!
After the end credits, the 100% ending shows an extra scene where Samus leaves SkyTown. As she does, a ship pursues her. The ship doesn't look like a Galactic Federation ship or a Space Pirate ship. Popular opinion seems to be that it's the ship of Sylux (one of the Hunters from Metroid Prime: Hunters), so either they're going to cram in more before Metroid II: Return Of Samus, or there's going to be a Metroid Prime: Hunters 2. Weird. The 100% endings of the previous games hinted at the next game so there must be some meaning to this, but Retro Studios said they're going to take a break from Metroid in a while so who knows?I may have to try to play Hunters again for my Metroid fix, since I got stuck in that game a long time ago and gave up, which is so unlike me...
Anyway, bustin, what I could do is start a new game on a new slot, replay the first half-hour or so to get a whole bunch of Friend Vouchers (the room of bugs makes it just a little too easy to get the ten "X00 Kills" ones) and send them to you. And then erase the file and repeat, until you have all the Green Tokens you need. If you want.
The "Bumper Stickers" are neat, I bought those with the two Green Tokens you've given me so far. They dress up your ship with icons based on the saved games of Nintendo titles on your Wii so far, like the Triforce from The Legend Of Zelda: Twilight Princess, and Mario's head from Super Paper Mario, among others. I guess I'll need to play Excite Truck and Wii Play at some point to get the two known "bumper stickers" that I don't have.
