Antwort im Beta-Forum:
Don't worry, you don't have to start from scratch when your base is destroyed. Actually you will be able to keep that exact base and build it up again. But you lose the territory your base was in and have to relocate it in order to start the repairs and get some new paint on your buildings again.
The conquerer gets the territory of your base though. Well, and your base's resources obviously. Wink
So you can defeat another player and claim this base's territory as your own, but you cannot "destroy his game".
A battle lost does not mean that the war is over!
