My Game - Wizard Realms - How to Score???

[taggartm]

When you complete the map I want to create a much better ending and include a score for the game.

I need suggestions and, if possible, examples. I know with Heroes the number of turns you took to complete a map was the main factor in the score. Should the same thing apply with Wizard Realms?
Possible other items to include in the score would be % of the map uncovered - did you find everything in the map - Total experience of all your pieces.

I also want to add 3 difficulty levels to the game. First time players will get lots of bonus drops and the Aztec Generators will churn out Aztecs at a lower rate. Players who breeze through levels 1 and 2 can take on level three where they will get - swarmed! <g>

Let me know your thoughts!
