Traversing forests and training higher level beasts becomes life-threatening when the magical monsters aren't nice by default, you can't really reason with them, and they're are actively looking to eat you. Human ingenuity takes more of the spotlight by necessity, as opposed to coaching skills or the bond between trainer and pokemon or all that fuzzy stuff.
Essentially, what I'm saying is that Pokemon become either purely tools for people or purely forces of nature, and you're left with just a Man vs Nature or Man vs Man narrative. It allows you to tell a different sort of story than a setting more resembling of the anime would, which is great if you're into that kind of thing.
