ArcheAge has a Karma system
Getting Karma Points
IF you gank someone his blood will be splattered everywhere(It's kinda gory) and witnesses to the crime can pick up the blood and submit it to a NPC, (just click on it in your inventory) and report it. Every time someone reports this you get 1 Karma point.
Also if you If you decide to steal something from someone else (ie steal someones crops or rob someones house), you will leave behind footprints for each item you steal. (you are given a pop-up window to confirm that you do in fact want to steal their stuff). Players can pick up these footprints and report you for the crime. Again you will get 1 Karma point each time you get reported.
Once you get to 50 Karma points you will be branded an outlaw, and a bounty will be placed on your head. The lucky player who defeats the outlaw gets the bounty and the outlaw will immediately go to jail to await trail. While in Jail you can search for items that may help you escape prison just in case you are found guilty.
The Trail consists of 1 Judge and 4 members of the Jury. The Judge is either a player (players can become judges in the game), or a GM will be a judge. The jury is usually random people. The accused can make backroom deals with the jury(like bribing them or get a plea bargain.)
The Judge reads out the accused crimes and then follows what a normal trail would be like in real life. At the end the Judge and the Jury vote (the vote is out of 5). If the accused is found guilty they get sent to the Prison. Jail time is usually 75 mins. or longer depending on how many crimes you committed.
You serve your time in a prison cell. If your on good behavior the NPC guards will let you out into the courtyard. You can escape or you can play the mini games in the prison to try and win that Prison costume. If you do escape you will receive a 50% debuff till you served your time. So unless you have friends on the outside, you might be in trouble.
There are Forgiveness Quests all thought the world. So if one want to get rid of their Karma they can do these, but these quests are long and hard to do.
Becoming a career Pirate/Criminal
If you want to become a criminal/Pirate full time, you need to accumulate 3,000 karma points. Once you do this you can go to Pirate Island and do the quests there. Once you compete them you get a massive buff, and can create a Pirate guild to rule the world.
But it does have some downsides, you will always have a bounty placed on your head. So another player can collect and you automatically go to Prison ( you get no Trail) and you can be in Prison for a long time. NPC's on the other continents will be red and kill you on site.
And some video's below showing the prison
Here are some videos from the Germans.
Evil Fido has been going around ganking lowbies and stealing from other players. In this video he is stealing Trees from someones Tree farm.
Notice when he steals something he leaves footprints. Anyone can pick those up and take it to a NPC and he will get a Karma Point.
Eventually Evil Fido got a bounty on his head and a player killed him. In this video he is sent to jail to await trail, but the trail came up right away.
Notice the Judge read him 5 pages worth of crimes. He had no money to bribe the jury so he was voted guilty, and his punishment was 120 mins in Prison.
Eventually Evil Fido was let out of his Prison cell and allowed to wander for good behavior, as you can see he wanders around to collect the Prison costume, you can also see a couple of mini games you can play while your in there as well.
