I as well firmly believe that an extra sum should be given for expenses like bribes and other cred spent in legwork--as well as expenses incurred like ammunition expenditure and the like.
I disagree - I think that the run payment should be a single figure (half up front, half on completion). The Johnson doesn't want to know details, they want the job done deniably. So the fee is X and how the runners spend it is their problem.
I agree that over the course of a month, they should be able to pay the rent, replace lost gear and save for upgrades, but it shouldn't be made explicit.
That is what negotiation is for. Otherwise known as "80% of the reason you have a Face on the team."
Which is fine in many games, but I think some of us are (like always) coming from kind of a
Missions-centric point of view. I know we're encouraged, there, to work up pay on a "per-runner" basis, and to keep negotiations fairly straightforward, because there's no guarantee that there
is a Face on the team, because no one knows if this group of six-to-eight random strangers is going to work together well enough to complete the job (much less to share the pay evenly between themselves), etc, etc.
Most of the time I hear the "individual payment" argument come up, it's because someone has been playing or running in convention games, and just wants to keep it simple.
