If you want to keep the game start blowing up Twitter and posting about the game EVERYWHERE! Killing a game that people enjoy playing is just plain stupid. They could easily put a small amount of development effort into this game with all the game development studios with recent purchases.
Here are some Twitter accounts to start blowing up:

We could also start a hashtag #SAVEAOECS
1. Write articles in tech forums
2. Complain to the media about it - negative news always gets attention
Don't quit and throw in the towel!
