[Marvel] wouldn't the Reality Stone just control, well, all aspects of reality? What's the need for the other stones?

The Reality Stone lets its user alter reality on a whim, but only in the local area and temporarily. 

* The Time Stone is needed to make these changes last.
* The Space Stone is needed to alter reality on a universal scale.
* The Power Stone is needed to give you enough power to alter permanently alter reality on a universal scale.
* The Mind Stone is needed to give you the mental fortitude to permanently alter reality on a universal scale.

I don't know where the soul stone comes in, but at the very least you need the four other ones to control reality like that.
