Canon: How bound do you feel to it? Options

[Paul]

Another topic got me thinking-how bound do you feel to Canon, and Rules as Written? For instance in my own games i think we emulate the spirit of Shadowrun quite nicely. But if a rule or a part of the setting doesn't serve our needs we won't hesitate to change it. It's actually not a lot of rules changes on our part-however our setting has had several changes, most minor but a few major.

The major changes:

• Cash. I get the arguments toward electronic currency, however it neither suits my tables needs nor our views of the Dystopian future. So at my table you can still get paid in cash.
• The Wireless Matrix has been shifted, not eliminated but rather it's role has been mores specialized, and formatted to make what we see as a little more common sense. it's not something that really changes too much.

I can't think of any other serious changes we make.

What about at your table? How do you feel about changes to Canon or Rules as Written? How often do you do it?
