Traditionally, PHost has the myth of being much more complex, much harder to set up and to use than HOST, for both host and player side. This document tries to help those who use PHost for the first time, to see it's not actually that hard.
At some places, mainly combat, it is indeed a bit more complicated than the standard VGA Planets host. PHost replaces parts of the VGA Planets host side, so some changes must be done to the client side, too. But once you've set up everything -- which is easier than you might think -- it will work seamlessly.
This document partly assumes you have already played VGA Planets before. If you have not, we suggest that you start with the Rules document, which will give you an overview about what this game is all about.
