Play Runescape Classic
Only existing RuneScape classic members can play RuneScape classic,

Only two types of account can play RuneScape Classic: those who played RuneScape Classic at least once from August 3rd 2005 to February 3rd 2006, and those who played in the two-week open period from 11th November 2009 to 25th November 2009.
