Players Options (Why?)

When the Darksun and Planescape player's options came out, I felt that a
version for Spelljammer HAD to be done.  While looking at all the PO stuff,
the thing that kept coming to mind was: munchkin!  What an out of balance
system.  You could really create some killer characters.  Don't know if I
would every use PO myself, but had fun creating the SJ version. Would like to
hear feed-back from a DM that actually uses PO.  Maybe it works better than
it seems (I don't want to give it an unfair rep, since I have not used the
system).  I dropped the Hurwaeti and added the Pirates of Gith since that was
the races I offered in my AC game.  Can anyone think of powers/race that I
might have missed.
