Replay feature
three forward speeds AND three backwards would be very usefull
the ability to jump to a specific point in time would be very usefull
Age of kings has KEY feature which showed you where a specific player was looking at any given piont in time...allowing you to 'see through the players eyes' ...this is perfect for commentary! , a must have feature
Important Note
Age of kings (and other games) allow you to turn recording off for slightly faster gameplay. This becomes more imortant as more data is captured. Thus the following three options are desirable.
Record OFF ( faster multiplayer games, especially for 6+ players)
Record Lite ( basic stats only)
Record Max ( for commentary and broadcast tournaments)
