Are there any plans to patch in a "Hall of Fame" page, where our highest scores are recorded? I really love this kind of feature, and it keeps me coming back for more even after I've learned how to stomp the AI on high difficulty.

Yes! I actually mentioned this in one of my Let's Plays.

Just like in Civ 5, it is always nice to access the statistics of previous games you have played, just to look back at your achievements and keep track of your playstyle
