I think it could be interesting to improve statistics at the end of skirmish or multiplayer games.
I'm thinking of something like Age of Empires end game statistics.
We could check the evolution of
- oil derricks
- units (for trucks, tanks, cyborgs, adav...)
- research done
To see what we did well or bad at the end of a game.
And we also could save these statistics to consult it later or share it !
