Capt. you always have gotten your credits for ghost captured just not the bonus for winning the game if the other team leaves.
Sad thing is that VMK tried to fix this problem in the "New" pirates game two ways...and People still do it
1. Charging to play
2. Giving credits even if you lose...I have made up to 200 credits losing a game of pirates...it does not make any sense what so ever to quit a pirate game when you can earn that kind of credit...with ghosts it is the same you still get you 5 credits per ghost caught so that can really add up if you are good.
All that said in pirates I have, a few times, gotten so mad

when I am on the Royal Team and the Team orginator has started the game before giving teammates time to chose a ship and have quit,not often, but I have done it. I told them why I was quitting though and then left the game. I admit I have not done this but a couple of times and it was a gut reaction to having had this done to me too many times on that given day.
Why because I feel you should give everyone the opportunity( Royal or Pirate)to chose a ship they like...I also do not like booting players and will not boot unless I have informed them as to why and it has to be a good reason(playing with a friend or playing with someone who's computer can not handle a full load of players).
I also told a player off yesterday for quitting pirates when his team was losing and found him on our dock when we came out of the game a few seconds later. The game had gone 3 rounds he lost a good amount of credits for doing that.
Ok my rant over so yes schnerk I totally understand where you are coming from.
