I just beat Metroid Prime 3 and I finished with 98%.  Has anyone gotten 100%?  Well, normally I sell the games I beat, but should I hold onto this for downloadable content?  Does anyone know if there is any rumor of downloadable content for MP3?  Just wanting to know if I should hold onto it for a while or not.  Loved the game by the way!

I got 100% on my second play through (on veteran, not finished with it yet, I stopped right before going to the final area).

I doubt we'll see any notable downloadable content for this game.

I regretted trading in games I enjoyed moderately or more, because I occasionally get the desire to play through them again.

I am married with 2 kids so that is why I normally sell games I am through with.  I am very limited in my game time so I am very selective in what I play and how much I play.  Good to see you got 100% though.  I guess I will sell it then.

First playthrough was 72%, second was 45% because I was going as fast as possible, third was 100%.

100% first playthrough at 15:46

If you still have your last savegame, the items you could have missed (if you used the observatory) are either on the derelict spaceship or in the ice area on the 2nd planet.

must you post these posts? I haven't even played it yet being from the UK and Nintendo treating us like a ginger haired stepson and all that.

Next Friday when I get the game - i'll let you know

100% thanks to the treasure map. First play through was around 24 hours. I putz around and check every nook.
