Actually the pointing of the arm canon at the Metroid is more logical since she was told to destroy all the Metroids...
Well, I'll not get into the reasons why those sequences are different since you still keep glossing over what the game flat-out tells you, opting instead to tell us what
your interpretation is. Rather, you said "You could argue Super Metroid, retconned Metroid 2" and my answer is I
could and I
did: Super Metroid retcons Metroid II. That's not debatable.
Let's also not forget in the opening sequence the hatchling is likened to a small child. Indicating...
Except that the Metroidhatchling is a small child seeing as it just hatched. You keep saying A indicates this or B suggests that while ignoring the fact that Samus tells you her motive.
Samus: I spared the Metroid so it could be studied.
Golden Phoenix: No, bitch, you didn't. I'll tell
you what
you did...
Anyway, I'm curious what Sakamoto would have said in 1994 as opposed to 2009.
