Either a Tech that would unlock the ability (or just a game menu) that would allow a player to compare (on a graph) different aspects of a players status.  (ie compare dust output, tech output, fleet strength, etc).


This could be implemented into an espionage idea, or just a tech that would unlock this kind of "spying", or perhaps even a ship or "Hero Type" that can be "inserted" into an opposing system to allow "spying - graph comparison".


More real time information on comparisons is missed (which is readily available in other civ type games).
