I'm quite happy this evening as I finally finished a Metroid Prime game - #3: Corruption on the Wii. I never finished 1 or 2 (and I had two attempts at the first one) as I would always get stuck on some well hard baddy near the end. This time, I've had barely any problems at all. This could be because:
a) I am older, better and more experienced
b) The Wii controls make things easier
c) It's an easier game.
I'm going to go with a).
I'm really tempted to go and have a final stab now at the first two...
