I got this game today, i've only played it for a little bit. So far I have got the super missile. But I died soon after, so i've got to do a lot of stuff again.
This is also my first playthrough of the game.
I really enjoyed Metroid Fusion, so i'm sure i'll love this game too, but having recently finishing Metroid Fusion, some of the secrets (which i'm sure would be very difficult to figure out, if you've never played a metroid game before) were quite easy to find/ figure out. But I am near the start, so that's expected.
So far it was a good purchase.
