I would love to see fatigue, elevation and terrain have a greater effect.
I would like that too. On MTW, i found it incredibly cool, watching as my men chased after the slow moving enemies. Much better than on RTW. It was also realistic how your men would go slowly up hills when you charge to the enemy, so it would be difficult to attack if they were at the top of a hill and you the bottom.

Remove ALL fantasy units. Especially the Egyptian ones.
Could you please give me an example of fantasy units? The only ones i know of are the british head-hurlers.
