I've got to agree with Joe; (spoilers) I was very, very dissapointed to see that the other hunters were quickly corrupted and killed. At the very least, I hoped you'd be able to save them from their corruption, so that the possibility of other hunters that AREN'T either dead or wanting to kill you for some reason could maybe arise in future games. Samus is badass as a loner, but having those other hunters to impede, aid, or just meddle her progress was a feature I, among many others, was very much looking forward to. The hints at a rivalry between Samus and Gandrayda (Sammy, rofl) was one of the biggest potential things, and they just kind of dumped it off. Dissapointing.
