PHost allows any player to play any race in the game. This is accomplished with the PlayerRace config option. This option has 11 entries, with each entry specifying the race that the given player is to play. For example:
PlayerRace = 1,1,1,1,1,6,6,6,6,6,6
This has players 1 through 5 playing The Federation, and players 6 through 11 playing The Borg. Values of 12 and larger are also accepted, meaning that the given player will have no special racial abilities.
(4.0) PHost 4 goes even a step further and allows to customize the special missions available to the player separately, using the PlayerSpecialMission option. This is intended for design games with custom races. By default, that is, if the option does not appear in the config file, it has the same value as PlayerRace.
An example for a completely non-standard configuration would be
PlayerRace = 1,1,1,1,1,6,6,6,6,6,6 PlayerSpecialMission = 1,1,2,2,2,4,4,4,4,4,4
Here, players 1 and 2 play standard Feds, player 3 to 5 play Feds that can Hiss instead of doing Super Refit, and all the Borg players can Pillage planets instead of Self Repair.
