I just got an 8 gig USB drive and am loading the game onto it now. Will give impressions on it as soon as it's ready to be played.
EDIT: Playing it. Love it so far. The d-pad is quite comfortable to play with and the action works well. The graphics are decent, but a little dissapointing. They're about the standards that the PS2 MGS games were. I know there's nothing wrong with it and that's still impressive, but almost ten years later, I expected a little bit more. It won't wow anyone like the Prime games did, everything looks very simplistic and minimalist, which is a bit contrary to most Metroid games, where I expect to see goo falling off the walls. But it's okay. The gameplay itself is quite good. Everything works as it should. Morph Ball doesn't move as realistically as it did in the Prime games, but it's still okay, and you can jump with it from the beginning.
