Without specific guidelines and working off a few very simple design principles, the designers went back to what Michael referred to as Swiss classical graphic design but adapted it for the digital environment, which meant adding things like motion and animation effects.
The parts you should pay closer attention to are the code patcher, which modifies the Morrowind game executable, and the selection of graphic options based on what your hardware can take, complete with previews (for example, water effects with OR without foam).
