Now onto topic: as several people have pointed out there are many levels of game, from street gangers barely scraping by to high-end prime runners stealing the corps' most heavily guarded secrets. for convenience I'm going to try and quantify this awesome:
1) Low street: you're mainly running against gangs, payouts mean that you just scrape by, and the only reason the Mafia or Ancients don't crush you is that they don't care enough.
2) High street: You're a respected name in the local z-zone, can afford a lifestyle and a safehouse and still have enough cash to upgrade that wired reflexes after a couple of weeks saving. Your employers tend to be large gangs or organized crime.
3) Low corporate: You're a gun-for-hire or similar, mainly employed by rating A or AA corps for runs against A or AA targets. It's the small league, but you can pay the rent each month and have enough change for a soycaf at the local starbucks.
4) Mid corporate: You've got a decent reputation, enough that AAA's are willing to hire you for less important work and AA's consider you on their upper list of 'get-things-doners'. You're making enough for a high lifestyle, a safehouse, and some new toys every couple of weeks.
5) High corporate: You're Ares' go-to guys for an extraction from a Neonet safezone, can and will take down Milspec targets for those that can meet your fee, and are generally the cream of the shadowrunning crop. You're swinging a high lifestyle and multiple safehouses, or maybe even a luxury lifestyle, and can impulse buy most standard-grade 'ware.
6) Super-high corporate: You are a matrix meme on par with Chuck Norris, command fees in the hundreds of thousands or even millions of Nuyen, and are hired when an impossible mission cannot fail. You swing with a luxury lifestyle and then some, can impulse buy Milspec tech, and might even be a lurker on Jackpoint.
Note that a campaign can and will change styles, and that there is overlap between each section in this non-comprehensive list.
My current campaign is both a 2 and somewhere between 3 and 4, with some payouts barely worth getting out of bed for on the face of it (Secure a corporate facility for a grand apiece, though as the facility in questing is deltaware-capable it's worth it solely to get the contact) and others paying suspiciously well (an infiltration mission is looking to net us about 30k each, and we're waiting for the other shoe to drop).
So where do your campaigns stand?
