If you have the Japanese copies of Mystery Dungeon: Shiren the Wanderer, Shiren the Wanderer DS 2, and Shiren the Wanderer 3 (released in America by Atlus as Shiren the Wanderer) then you might want to know that they will be going offline coming this November. The servers will be shut down on October 31st, SEGA announced today.
That means stuff like leaderboards, time attack rankings, item trading and the rescue system will not work in the games anymore (at least the Japanese versions). It is not confirmed how this will effect the other versions of the game.
Only the SEGA published Shiren the Wanderer games are going offline, so that means Shiren the Wanderer 4 will still be online for the world to play.
