I would guess that you are equating position equality with all positions being clones of each other. That is certainly not what I meant, I don't think it is what I wrote, nor is it what I believe anyone else has been talking about.
Hyborian War does an excellent job of making sure that a strength in one area is balanced by a weakness in another and that the odds of winning, given any particular set up is equal to the odds of any other given set up - otherwise it would not have lasted this long. I suppose, in theory, it would be possible to balance off having to colonizable worlds in a home sector, but it is such a big advantage - almost as good as getting to play two positions - that the dowside would have to be equally huge.
