But really, where are those damn rails? I got to thinking about this a while ago while playing through Pokemon Black 2. One of the additions the developers have strived to achieve is a sense of place. Meaning that objects are not just obstacles but actually make sense. The walls are covered in posters, decapitation looks believable, and there are damn rails where there should be.
It’s a volcano, not a place for tourists. Also, it’s not like you can even walk into the lava. If you want realism ask about the little cliffs you can only go down. I think I can climb up a 4 foot ledge.
