I voted no, but I'm not totally opposed to the idea. It's mostly because I feel like it would be just another rock in the basket of 'just rush to the next era, go go go' and it is pretty full as it is, while, IMO, what HK needs is not even reasons to stay behind but maybe even outright some kind of force to do so (I still hope we eventually get the amount of stars required to advance as something you can change in game set-up, especially if we, finger crossed, get another expansion with its own set of stars like TWR).

I hear your complaint about not many chances to catch up with Fame outside of stars and I'd agree that various achievements side of Fame is rather poor comparing to how much trickles from stars. I wonder if they wouldn't need a major buff in general, so they fully become another source of Fame rather than being just a little extra on top of what stars provide.

I totally disagree. The number of wonders already grows with the ages, especially since it tends to snowball, because the most advanced empires usually end up buying them all. So the disparity would only increase. I think it would be more impactful to encourage mastering each age rather than rushing to the last one.​
