One of the biggest problems I had with Metroid 2 [granted, I haven't played it probably 20+ years] was how it was so, so easy to get completely lost and have no idea where you supposed to go next.
Also, if that fact sheet is anything to go by, it sounds like they're going more for Metroid Prime 1 than Metroid Prime 3 [or they could be referring to those DS games], which I'm fine with.
