VGA Planets is a shareware game. Like the original game server HOST, PHost enforces the registration rules: registered players can use some commands that unregistered players cannot; only registered players can buy all tech levels. If you want to use all features of the game, you must register an original client program (DOS Planets or Winplan) with Tim Wisseman. Third-party clients usually need such an official key to generate registered turn files.
See Registration in the Glossary for details.
