But other things are almost impossible to mod. Adding your own terrain tiles is one of the latter because of the random level building. New monsters are a major pain because of the way the sprite animation is done. I did manage to replace an NPC or two, but it didn't add anything significant to the game so I quit trying to mod it.
As with Dungeon Siege, I found some of the later enhancements weren't. Runewords were kind of a pointless variation on gems for socketing - the idea of adding your choice of enhancements to your equipment had merit - but the methods just got too complicated. I hope they don't continue that trend in Diablo 3.
