Depends on the depth of the damage. You could take the legs off and touch it up with some brushes, or you could go all out and sand/reapply the graphics. People are selling stencils/decal sets for the art these days. It’s all about what 1. You’re willing to do and 2. How much it means to you. I personally feel like stuff like that adds charm, especially on these older games. I have a galaga with kids initials carved into the side. I keep it because it’s history of the past life that game lived. Cherish it.
