I can't remember if I posted that I started playing Metroid Prime. It's got a lot more of the 2d Metroid dna than I expected, but at about... I'm guessing a third of the way through? It feels a lot more linear that most Metroid games I've tried. I'm not sure if it's because it's actually more linear or because of the hint system that slowly pushes you towards the intended path. I tried to sort of "defy" the hints at one point and take my own path, and ended up with nothing but dead ends.
