My scores are based in these four categories:

• Visuals:      [1-5]
• Gameplay: [1-5]
• Audio:         [1-5]
• Story:          [1-5]

And then the average would be the final score. As this site uses a scoring table of 1-10, my scores are scaled to match. Which means that I only use even numbers when scoring.

If a game doesn't have a story (e.g. Mario Kart 64), then that category is not taken into account for its score.

Anyway here is a beautiful Skyrim landscape:
