Silent Hill did this and everyone agrees it's a masterpiece!
You're comparing oranges to apples. Silen Hill is a horror game, and not knowing where you're going or what you can find helps the atmosphere. Pokemon is not a horror game, it's an RPG in which exploration in search for pokemon and items plays a fundamental part, especially now that they are focusing so much on the open world aspect of it.
You know it deserves the GOTY.
