I think the problem is that the game is not inherently different in each age, much of it feels like you are just repeating yourself and moving ahead incredibly slowly. Its that lack of momentum that kills it for me every time. Someone mentioned earlier that the first age should be setting yourself up for the implementation of your plan, but it never feels like that is what you are doing in the game. Mostly it feels like someone just kicked your sandcastle over and you need to build it up again. I think the problem goes far deeper than smoothing out the transition as well, which is what the devs are concentrating on.
I think if you smooth over the ages and also rework the legacy paths, it could help solve this. Smoother age transitions would help create more continuity so that it does not feel like you are starting anew. And if the legacy paths connected with each other, then it might help the player feel like the previous age was setting up a plan to then implement in the next Age. For example, if the science legacy in the Antiquity Age was setting you up to do the science legacy in the Exploration Age or if the culture legacy in the Exploration Age was setting you up to do the culture victory in the Modern Age.
