I played for a week or so before deciding to stop playing and that it wasn't worth buying. I had some observations: First, it was unstable. Unless the client was restarted after every game or so, after a game or three it would screw up and ships would start teleporting around and the game would be effectively unplayable. I tried restarting during a game where it was doing this, and it kept doing it after I restarted and rejoined the game, for a couple of seconds, and then it crashed. I was unable to rejoin after, and was given a desertion.
I would occasionally meet enemies with ships who were so powerful that it was impossible to defeat them in combat no matter what, as a result of the way the game worked - the way it gives you loot for winning battles, less or none for losing, and better loot if your ship is a higher mark number (which you have to have played for a good while to have achieved, and paid for). You can't obtain the loot that paying players get if you have a mark I ship, so whether you're just new or haven't paid, your ships will be inferior.
I would not want to waste any money on the game when it may become unplayable in the future, even the near future, since the desertion counter has demonstrated an ability to go up through no fault of your own (as it has for me), and could easily go up again due to a power outage or internet failure while playing (even if I managed to avoid triggering the same bug that made the game unplayable and then crashed it). The only way to get clear the desertion counter is to make a new account (losing your ships and paying status, if you paid, I expect), and people's attitudes towards it are "That person is a deserter! Don't play with them!"
