Changing map won't resolve the problems anymore. We already sawn it with C18...
It brought back some players such as desertos, yes, maybe. But he also came back for 1-2 week and I didnt see him anymore. The server are now back to their original state : Nearly empty. The world evolve and new games comes out, you got to live with it. HL2DM is getting old and boring, player want to experiment new graphism ! New gameplay ! New story etc etc.
