There IS no real point in downloading this other than saving disk space. You could just as well download the old versions and play them. The only thing you would miss are Glaber's (misspelled) comments on the maps.This would be better if it was an unlockable for the current version. Then again, why can't we just play the older version? Except for playing the old levels in multiplayer, I see no point in downloading this.
