Subgame
From ASSS Wiki
Subgame (or Subgame2) is the alternate server to ASSS. It was originally made by VIE, but was edited by PriitK to support Continuum. Using more memory than ASSS, it does not have nearly all the features that ASSS has, nor is it open source (it was written by VIE). Subgame works in connection with a Billing Server to allow users to enter a zone. Old and stable, subgame is used by most zones today.
