Sky Render on 04 January 2009
The biggest issue with the Prime series is that it does try to take expectations and reverse them. That's not how intuitive games work, and is actually why Prime 3 has a bit of a counter-response to the problem by having more enemies to fight and more one-on-many brawls. Intuitive games take your expectations and run with them; if they're especially good, they take those expectations to new levels. But Metroid cannot do that with first-person perspective and expect to succeed. The concept is just close enough to that of an FPS to be incompatible. Hence why I say a 2D entry is the best bet. Or a third-person 3D entry, possibly...
Sky Render - Sanity is for the weak.
