Oh, I'm seriously compellled to play through Corruption a third time.
I have not stated it here, but since mid-September, I played through the entire Metroid Prime series after completing Corruption the first time. It took me about a week and a half to complete Prime, a bit less than a week to complete Hunters, another week and a half to complete Echoes, and another week and a half to complete Corruption.
I might kick it into high gear and choose a harder difficulty this time, though...
