I recently came across a interesting mechanic in Mongoose's Legend system that I am considering using in SWSE.
If you haven't read it Legend is currently available from drivethrurpg for $1 http://rpg.drivethrustuff.com/product/97239/Legend?language=en
It's a pretty good percentile system, but back to my intended point of this post.
In character creation there are a few random tables for character fluff, how large your family is, the family's reputation, and connections. Sure some players would prefer to just make that up, but I don't think many would mind having rolled a random Uncle with underworld contacts.
This would limit the "I have no family" character and gives the family a story. Even if the player really wanted to play a character with no family, the difference between a poor family reputation and a good one would dramatically change the way the world perceives that character.
Now to the "meat" of the post.
The next random table is "Backgound Events", it is a d100 table with potentially important events that have happened in your life. Obviously if what you roll doesn't fit in the character concept re-rolling is encouraged. And most events are a little vague so there is plenty of room for the player to spice it up.
For instance you could roll "saw a great battle", "family secret", "Inheritance denied", or "raised by Trolls"
However what make this incredibly cool is the option of "Connections" it involves at least 2 characters. If both players agree then any event rolled can involve another character. Perhaps you both saw the great battle or the other character inadvertently learned your family's secret.
Now in Legend their is a mechanical bonus to get PCs to do this. You can have 2 bonuses each with different character. So you roll on the table and Bob connects to you, then Bob rolls and Sally connects to him. Bob gets 2 bonuses.
The bonus is +10% to any skill they already learned in character creation. I think this could be changed to a +1 for SWSE.
Anyone who has played Spirit of the Century (you haven't?) knows that starting the first game with adventure hooks for the GM, and having the characters connected previously so there is none of that weird/boring "you meet in a tavern" roleplaying is awesome.
Legend is somewhat gritty fantasy setting. Some of the events on the table could fit very well in a Star Wars game.
"Met a villain at a time when relatively unknown" - Obi-wan & Vader
"Family secret" - Luke learning is father was a Jedi.
"Father Died or Killed" - Luke learning Vader is killed his dad.
"Mute" - Han translating for Chewie (I know not really mute, but the flavor is there)
"Twins" - yeah you get the point
However some don't really work as well. I am slowly going to start working on a SWSE table. My understanding is that Traveller uses background tables so I might peruse that to see if I can find some more sci-fi event ideas.
If anyone has a good Star Wars Trope or cliche they would like to share I'd love to hear it.
