With new spyware added to it this great game is no longer playable. Is there any alternatives, similar games? "Children of dead Earth" is great one, but it too militarised.
Please provide more information about this new spyware you're talking about. Whatever it is though, you can add a rule to your firewall to block all outgoing traffic from KSP. Other than that, give this one a try: http://orbit.medphys.ucl.ac.uk
KSP now shipped with Redshell "protection". Which is nothing but spyware. Just rear licence agreement you need to sign.
