Something I don't see people talk about enough is the pacing. I binged through it when my parents were out of town, and as long as I was following the story (not backtracking for stuff like missile upgrades) I swear I hit a save point every 30 minutes. There was never a time where I thought "I haven't saved in a while" where a save point wasn't right around the corner.

And the gameplay was great.

Except for the forced first person locked in place mode for missiles, especially during the final boss where you'd get shredded the moment you stopped moving.
