When you run, your ship occupies a smaller area to your opponent, which means that your manoeuvres count for less, which means they have an easier time hitting you, which means you die. So running is often not an option if you're attacked by a player.
The combat mechanics are why I'm turning off multiplayer as soon as I can. I'd *like* to play multiplayer, but I see nothing to indicate that they will ever be fixed.
The problem is time. Everything takes quite a lot of time in this game - except combat. I've been killed by other players in less time than the computer takes to announce 'you are under attack'. After spending several minutes flying somewhere, this grates a bit the first time and eventually became what has stopped me from playing the beta. Shooting down someone on a trading run takes seconds, but can wipe out hours of work.
If combat were changed so that it was more strategic and so that even an experienced player would require a lot of effort to finish off a complete newbie, it'd potentially be way more interesting. A player beset by pirates would have time to call for help, and there would also be time for help to arrive. Pirates would have more reason to issue 'stand and deliver' orders (because it saves time) and players would have more reason to comply (they don't end up being chased all over the system for the next 15 minutes).
Bounties would need to be increased to make bounty hunting worthwhile, but I can't help feeling that getting a large bounty after a long chase is going to be way more satisfying than the current situation. I'd love to see the mechanics change so that you don't die unless your opponent really wants you dead: if I have an hour an evening to play, then getting killed basically wipes out everything I've done in that hour. I'd like to think that the person who killed me actually earned it.
This nicely fixes the problem of where your opponent has a ship that vastly outclasses yours: it doesn't matter. You can run, you can call for help. You have options, instead of what exists now: which is you can die, or you can ram him to express your displeasure and then die.
I don't expect to see anything like this. I expect the final game to still have short combat, because nothing I've seen in the design documents indicates otherwise. So it'll still be a dice roll as to whether or not any given instance will contain someone who's bored and wants to kill someone. All of the mechanics I've seen focus on punishing that player, but that doesn't help me: my evening's gameplay is still ruined by that random chance.
So, the combat mechanics mean no multiplayer for me, because all it seems to add is a random 'oops, you rolled snake eyes, you're dead' element to the game that simply isn't ever going to be fun, an effect made much much worse by the time investment that it demands.
