What is it that separates this version of Star Wars from the others? Someone mentions something called Obligation so what is that in these rules and how does that work?
Hard to say without any fore knowledge of the others.... However
Every character in EotE starts with an Obligation of some form to some one (or some group, or some thing). This is represented by a numerical value which indicates the strength of the Obligation and a type. These can be determined randomly or chosen based on character background.
Examples of Obligations are Addiction, a Bounty on there head, a Debt to pay, Family or a Favour owed. Sort of like how Han had a Debt to Jabba, that became a Bounty. You could even say Luke had an Obsession to find Leia.
You pool the values of the party Obligations to get a value usually somewhere between 40 and 60. At the start of each session the GM rolls percentile dice and if the result is lower than the combined Obligation Pool then it is triggered and the group suffer a penalty during that session, as the pressure of the obligation takes effect. The GM can choose to leave it as that or actually have something related appear in the session, like Bounty Hunters turn up for example.
There are about six pages on Obligation in the character creation area and another four in the GM section, so I'm leaving a lot out. Like how you can lower or raise your obligations or gain them in play or what they might mean to other NPCs.
It seems to me that Obligation is particularly suited to the campaigns Edge of the Empire is designed to support, it isn't something I'd expect Rebel commandos to worry about in the second book, or Jedi in the third.
