It is Havok Engines fault it gained it's bad rep with alot of bethesda's games mostly because of the freezing but this new problem with the unreadable disc is no better. I wish they would use another engine like source, unreal or even chrome.
The game's engine is a slightly improved Gamebryo engine, which was the broken engine they used in Fallout 3/NV. --- "If history is to change, let it change! If the world is to be destroyed, so be it! If my fate is to be destroyed...I must simply laugh!!."- Magus
