I think ES should completely redo AOE & AOK and make something similiar to AOM. Of course you will have to get rid of the whole mythical part. Things to include or change are:
Generals: Each time you age up you choose a general. Different generals gives you different units, research, command power, as well as formations (which is a button on the UI.)
Animal Population: Any units which require a horse will cost 1 animal pop, while a unit with 2 horses requires 2 animal pop, etc.
Neutral Units: Units such as the catapult, or trebuchet can be taken over by anyone. (Im not sure exactly how to kill the humans controlling it)
Resources: Food, Wood, Gold, Stone (yep the stone is back)
Command Powers: Similiar to the god powers in AOM.(also similiar to the ones in C&C Generals which I dont have yet)
Formations: Different generals come with different formations, such as a triangle or two combined triangles. Theres also speacial strategies like hoplites actually pushing back enemies.
Unique Units: Instead of 1 or 2 unique units almost every civ has their own unique unit skin and stats from the beggining.
Unique Buildings: (same as above but for buildings)
Garrisonable Walls: Most walls can be garrisoned with archers to allow the walls to fight back. Also their is a research which allows the walls to attack without garrisoned units, but is weaker and costs some human pop.
Moving while attacking: Not all units sport this but units that are on horseback and have a bow can fire while moving.(prob unlikely but they did it in Generals)
LOS: Walls, towers & gates have NO LOS. Unless researched (costs human pop) or garrisoned.
Well thats all I can think of (for now) I'll prob rethink this stuff and decide that it doesn't belong. This is after all an opinion (a long one). Im sure that whatever ES creates for their next game will be awesome as their 3 other ones are. Thanks for listening, err umm for reading.
