Prestige

You could allow players to prestige to start again but with a bonus either economic or military. You would obviously get to keep any of your gem purchases but get bonus to production or improvements to specialists. Maybe a better island to start with?

I've wondered why they don't have prestige, too.
Better than leaving ppl stuck at level 50 for so long.

They want us to be stuck at level 50 for 5 years well they laugh at us for being so bored >:)
