It really isn't that much worse from every other 3D platformer. The most egregious thing in the first one is having to get almost all of the musical notes. But jiggies are just symbols of completed missions, Jinjos are pretty much just red coins and can be skipped, and everything else is just ammo.
in Banjo Tooie all of the collectables come in packs of 5 so you collect way less of them and your ammo is always maxed out. And they scrapped mumbo tokens, you just have to collect one little dude that is usually 5 feet away from the transformation hut.
