RuneScape has announced a closing date of March 22, 2014. That means, after this date, RuneScape will become inaccessible to all players. The reason for closing has been stated as there simply not being enough players to keep the game online. Over the last several years, RuneScape has been in sharp decline as younger game companies are able to entrench on RuneScape's userbase. RuneScape's failure has been said to be caused by Jagex's underhanded tactics and putting out low quality game updates repeatedly.
It's a sad day, mostly because it was preventable, but one that many players saw coming for a long time.
