Sometimes, graphics just distract from the gameplay. Skyrim probably wouldn't be my choice for that treatment but some multiplayer games can actually benefit from it. Used to play Quake for a couple of years like this and learned to like it a lot. At first it was just to get more FPS, but then I realized that it allowed to better focus on the gameplay as well. There's a reason why some arena FPS even today intentionally go for these very simplistic graphics.
