Family can not play

I write reluctantly bad news about a game in which one has really been looking, I would have but know some things before I would not have invested my money in this game. About the graphics and the gameplay, I must not go on, this is absolutely in this game Top. The biggest annoyance for me is the following, however: my whole family plays the Anno series up and down like that older versions we all have to play twice and three times to the game on the network.

Full of anticipation so Anno 2070 installed on the PC of my son.
Successfully entered the serial number and performed the online activation.

My son has now played the first campaign and now comes the big drawback,
when my son on his PC has no desire to play the game and the next member of the family to play a round at his PC that will not go, we respectively have not yet figured out.

When trying to register an account the message that the serial number is already in use appears, that is also evident when entering the data of my son one lands in its settings, you can start any own campaign under his name,
then you have the campaigns of the son to continue what he is obviously not so great.

In short, other family members can not play from zero to the game itself.

I am not interested to network games, because it would be me obvious if you have to have a second game, but the offline play, on the same PC as it must be possible to start a stand-alone game or anzulgegen own profile.

The game gets me is why only 1 star because there is no 0 star here.
We are disappointed, had to save long in the game and now this.
No buy recommendation from me, I hope the manufacturers to improve here.
