I think that you you add more upgrades to the units. Maybe 8 steps from peasant to knight. Alternatively, you could just make it so the tech tree is easily modable. Then you can let the fans do it.
One of the reasons I am such a fan of modable games is that I think that they build a community arround them that keeps the game fresh. Also, such a community acts as advertising for your work.
