I only recently started playing SR again (I've been away since 1996

) but I'm going to bring back one of our old house rules. I call it the Lot in Life.
Mostly it is designed for players who are either new to Shadowrun and/or table top RPGs
Here's how it works.....
Your Lot in Life determines where you are in life just before we start our first Shadowrun session. It doesn't determine your backstory, race, species, or sex. It is simply a story telling tool that allows the player characters to mesh a little better into the world. An especially helpful tool for newer players.
The Lot in Life also allows me (the GM) to get you connected to other potential plot devices for use at any time during the campaign. If things start to slow down, or when you least expect it, something, or someone might come out of your past and turn what was supposed to be a simple B&E into a total Charlie Foxtrot.
Here is the Lot in Life list that players will select from.
1) Recently released convict tied to one of the Big 10 corps and very loyal to that corp. Family Missing
2) Last member of a gang recently wiped out by the Yakuza
3) Political Activist wanted by corporate security for acts of terrorism
4) Thrill seeker with a terminal illness
5) Unemployed and homeless because of a frame job by a corp
6) Average person. Family struggling to survive
7) Prostitute
8 ) Amnesiac with a connection to a Dragon
9) Used car salesman who sold a bad car to the wrong person: a vampire
10) Former member of a BlackOps team in the middle of a corporate cover up.
You can keep your LiL a secret, or share it with the group. But eventually your Lot in Life WILL catch up with you.
To discover your LiL roll 1D10 or 2D6 (with re-roll on 12)
You get what you get. Such is life. However, as with life, you are free to handle your situation as you see fit. It's all very generalized to give you the player all the customization options you need.
For example: If you roll 7 and get the Prostitute LiL it's up to you to decide how/why you became a prostitute, and how/why your character has opted to start Shadowrunning. You decide if you're a high class hooker or a 5 nuyen ho.
With each LiL there are pros and cons. With the Prostitute option you may find that you've got extra contacts you've made through your "work". On the other hand you may have also have a psychotic stalker who wants you all to him/herself.
To assist in customization all players will gain an additional 100BP to reflect their LiL. If you select the BlackOps LiL obviously that person will have some specialized skills coming in.
You can embrace your past or run from it in an attempt to reinvent yourself. Your reasons to run the shadows are your own.
If you're not happy with the LiL you've selected you'll get a d6 number of chances to re-select.
