Torchlight - Level Editor and Videos
Runic Games announced that the level editor for Torchlight will not come with the game. Instead, it will be available as a free download from Torchlight's homepage and various other sites. They state that to include the level editor it would make the download too laborious, especially for people who just want the game.
In addition, you can view 23 minutes of spoiler free videos at Runic Games Fansite. The videos are from the Endless Dungeon where everything is random and has nothing to do with the actual plot of the game. You'll see random enemies, traps, loot and more.
