In videogames sometimes "forests" have like two or three dozen trees. That's too few trees. Or they have lots of trees, but the trees are really widely spaced out. Twenty or thirty feet apart. Obviously, all of these forests are nonsense. We won't even begin to address the forests where the trees are too dense to travel through except on the main path the developers want you to follow.
For all its strengths, Skyrim is a game without good forests. Too few trees, and they're too small. No more! Building on work done in earlier mods, Fabled Forests for Skyrim Special Edition gives you "tall, dense, FPS-friendly forests to get lost in."
