IME, the 38 infinite planes, with multiple layers, leads to analysis paralysis. Unless the players are somewhat familiar with the planes, ie they are into the PSCS, then there is too much info for a DM to pass along. Making the default setting a bit simpler helps make plane-hopping relevant to more players and thus more groups.
I ran a successful PS campaign from first to about tenth level where none of the players had ever so much as looked at a PS book or the MotP. The trick is to give them only a very high-level view upfront, and fill in the details as necessary.
