Good Points
Many unique units inspired by the books
A diplomatic system
A pretty map
Bad Points
No restrictions on army size resulting in mega-stacks
Boundaries are hard to see on the map
The diplomatic system is fairly basic and results in a war of all against all in AI play
Note: Try this with all powers controlled by AI and watch the "Others" slowly conquer the map
