Considering they will not release a tool set for the console version, I think random dungeons would be a good idea. Either that or let the console people download the pc mods.
I would love see obsidian add some random dungeons for multiplayer. I'm tired of the same old 16 to 20 hour experience. Add some random dungeons for replayability with friends. I haven't played the previous DS games, but the current standard game length isn't that long.
