DR2

This was the layman's name given to a substantial behind the scenes upgrade to the IFE (interactive fiction engine)[1]. According to the DR Forums, the official announcement was made at SimuCon 2003. Player testing started in late April of 2004, with those that signed up for SimuCon getting a chance to preview the new engine in a separate instance. Later that summer all subscribers were given the chance to go find bugs before the official release which happened after Simucon 2004. While few changes happened immediately many systems were broken because of the upgrade, some of which are still in a state of disrepair to this day, including paid quests, like Dunshade or Corik's Wall.
