One of the first Skyrim mods, straight out of the gate, despite the Creation Kit not hitting the release-date. No Spiders. Replaces all spiders with grizzly bears, although it’s just a quick-fix mesh replacement for now. Personally I might have replaced them with one of the Morrowind monsters, but that’s just me. Doubtless there will be a mod for that too, in time, complete with suitable animations etc. Wouldn’t it be great if videogames allowed you to select the monsters in the setup, just like you select race, hair, etc?
