It makes me sad because I loved that game and remember how big of hit it was when it first came out.
I think a remake of AOK would be awesome. ES could use the 3D AOM engine and game style such as 'player decisions' at the end of each age.
The amount of civs should be increased from AOM but perhaps a little less than AOK (help reduce the size of the project)
I for one would love to see frankish Paladins and British longbowman not to mention trebuchets in 3D with improved sounds and visuals.
From a marketing perspective it could draw on both fan bases.
To make it feel somewhat different they could sprinkle in some new units, refine and balance older ones and to freshen it up introduce entirely new campaigns.
If anyone thinks they would love to re-live the AOK experience again please post here to show your support!!!
