Due to the fact some people find it amusing to inderdict me when I have no bounty or cargo and destroy me for the 'fun' of it - I have chosen to remain in solo play, and I think this is the case for many people.
At the moment it is far to easy to 'grief' people - the game is already unforgiving and even in solo play its easy to be killed accidently by NPC's ramming you as you try to enter or exit the space dock, or being killed by the internal weapons of a space station trying to shoot something on the outside (I managed to escape an NPC pirate and run to a station only for the station to blow me up in an attemp to kill the pirate).
I simply do not have the time or inclination to deal with people who think it's 'fun' to destroy an unarmed ship with no cargo, thats why I am in solo mode.
When I have made enough money to kit out a good ship for dogfighting, I'll certainly be playing multiplayer, but as it stands it very difficult to advance yourself as a new player, and 'griefers' simply add to that difficulty.
Hopefully some kind of system can be worked out by FD to stop indiscriminant murder.
