Way back in 2006 someone found a hack that removed the borders from Oblivion, eliminating the "you can't go that way, turn back" message when you hit a border. I tinkered with it for a while but for me the landscape editor is clumsy and tedious so I went back to doing what everyone else was doing, creating new dungeons inside the original borders where I didn't have to bulldoze mountains with a shovel.

Has anyone made new city mods outside the original borders at all?
