People these days seem to misunderstand cursed items in D&D. Players find some magic items and divvy them up. Then one player finds out that their item is cursed, and they now have some sort of drawback. And they probably bitch and moan a bit, and depending on edition and how high level the PCs are, they probably cast (or purchase) a spell to remove the curse, grumble a bit more about getting screwed over by the DM, and carry on.
But it's not intended to be that way. Back in the earlier editions of the rules, especially for cursed swords and armor, the rule was that if you could get the curse removed, the item then reverted to a beneficial item*. So curses were a means of providing an adventure hook.
If a player found a cursed weapon or armor, at low levels they had to deal with it until they could find a high level NPC to remove the curse (requiring paying large sums, a quest, or both), or go on a quest of their own to a location (in a dungeon or far out in the wilderness) where the curse could be removed. Getting a curse was a means of providing the players with a goal - remove the curse. And there was a reward to it besides just elimination of the penalty. The weapon or armor that was previously lowering combat efficiency would improve it instead.
Yes, this post is inspired by my 5E gaming. It seems like newer gamers just don't see the value in things like curses, save or die spells (a double edged sword, yes, but also fun!), or dwindling resources. And WotC seem to also have this mistaken idea that any sort of hindrance is unfun. Everything is awesome! Everyone is special! All the time! Well, to tell the truth, that's NOT fun. Getting cursed and then having to jump through hoops to get rid of the curse is fun and satisfying! Getting cursed (or level drained, or finger of deathed, etc.) adds spice to the game if it actually affects you. If you just need to have the party Cleric come over and cast a spell and it's over, what's the fun in that? Where's the challenge? Where's the satisfaction?
Probably more to come along this line of thought if I have time to blog again soon.
*Yes, cursed scrolls, potions, rings and miscellaneous items don't have this benefit. But it's easily house ruled for the permanent rings and miscellaneous items, isn't it?
