well, there are these wonderful little quotes from the book:
SR 5, page 333:
Next, table rules should be established, if the group
doesn’t have them already....
SR5, page 334
The group should then discuss if there are any house
rules they would like to implement. These are specific instances
where the group decides to play the game differently
than how it is written.....
SR5, page 334
When everyone comes to the table, they should
come with the attitude of dedicating themselves to the
game, committed to making it work. All of the discussions
described above are designed to help the gamemasters
and players understand group goals and expectations
and (ideally) find acceptable compromises.
SR5 page 416
Gear’s Availability Rating determines how easy (or hard,
or practically impossible) it is to acquire a needed or desired
piece of equipment. Availability is an abstract amalgamation
of factors like rarity, legality, distribution issues,
supply, demand, and so on. The letter that follows an
item’s numerical Availability Rating shows whether the
item is Restricted (R) or Forbidden (F). For this reason, the
gamemaster should feel free to modify an item’s Availability
Rating—either the numerical value, or its legality
code—in situations that would warrant it, like if the runner
is in a war zone or in a country with a restricted economy.
so here we have MULTIPLE references from the book that ALLOWS you to change things. and you can do so as RAW (because it is written in the book.)
it even goes on to tell you why some items have an availability!!! (can you find the quote that tells you why?) Sure that item is sitting on a shelf somewhere in some store, in some city, in some country. But it just might not be YOUR city, or your Country. Not to worry! They deliver!!! (see the delivery rules) And for a few (hundred? thousand?) extra bucks, you might be able to cut that time down do mere minutes! (which I guess would mean it was in the very first shop you walked into!)
Now lets ACTUALLY look at all the items listed in the book.... starting with the items with NO listing for availability (a dash):
Knife, Survival knife, Club,Defiance EX Shocker, Yamaha Pulsar, Clothing, (Synth)Leather, Helmet(s), AR Gloves, Electronic paper, printer, trodes, trid projector, datachips, standard RFID tags, Cyberprogram, common use, standard and silver credsticks, tool kits, Binos (all types), cameras, glasses, googles, image link, ear buds, head phones, Omni microphones, heck, you can even get metal handcuffs!!! (sex shops. they ARE good for something!) the list goes on and on but you get the point.
Everything on the list is pretty much your everyday affair item that you can find at any low budget Wal-Mart type of store. All of them are typically non violent (Tasers are seen self-defence items), or have other, more mundane uses (baseball bat for a club... a steak knife... for a knife). Heck many of these items you can get at a dollar store NOW. Most of these items are your run of the mill "trash" items that many characters never actually buy (I can't think of a single time I had a player write "paper for printer" on his character sheet...)
Now lets look at the items WITH an availability cost to the item, but no legal code:
Combat knife, Extendable baton, Sap, various staves, various firearm accessories (but not a single firearm...), taser darts (they are harder to find then the taser! Go figure), flash pack (WTF?), feedback clothing (is this so you can wear them, and THEY can tell you that you look like an idiot, before you leave the house? probably not....), various armor protection mods, various armors, every single commlink,, software of various types, good credsticks. the list continues, but you get the idea.
these are all the items that are perfectly legal to own and buy.... but you just can't walk into any low rent department store and expect to find them... you might have to put a little leg work into the actual search.....you know, buy it from Zoe's fine wear, instead of K-mart...... IF you have a Zoe's fine wear shop in your town.
now lets look at 2 items from the same category: commlinks for this example, we will use a low mid range and a high end item:
Sony Emperor (availability 4, $700 cost) this is about equal to your smart phone most of you have in terms of price point. (iPhone 5, galaxy S4, etc)
Fairlight Caliban (availability 14, $8000 cost) this well more then my sat/cell Ericson smart phone (it better be water proof like mine is!!)
First lets review the how and what the test is:
SR 5 page 418
When you get to the good stuff, the higher the Availability
Rating is, the harder it is to acquire the item. To purchase
an item off the books, make an Availability Test.
This is an Opposed Test of your Negotiation + Charisma
[Social] versus the item’s Availability Rating. If you win
the Opposed Test, you find the gear at the listed price,
and it is delivered in the amount of time given on the
Delivery Times table divided by your net hits. If you tie
in the test, you find the gear, but the delivery time is
twice that listed on the table.....
lets assume you didn't totally cripple yourself, and say you have a Charisma 3 and Negotiation 3 (plain old average).
For the Emperor, you are rolling 6 dice VS the device's 4.... chances are you will win by at least 1 success... maybe 2 (or maybe 6!!): now we look at the table for delivery times:
1 success: 1 day. so you spent a day wandering the city and found one! congrats! or you ordered it online with same day delivery.
2 Successes: 12 hours, so you spent half a day looking, and found one. good job!
6 successes: 4 hours.. so you hopped on a bus, went downtown and found one. Next? LUNCH!
on the opposite side of the spectrum, you go for a Caliban! same average Joe as before:
Now you are rolling 6 dice VS 14.... and chances are GREAT that you are not going to find one. Maybe they are sold out. Maybe there was a problem at the factory (damn shadowrunners! They are ruining your consumerism!) well, at least you are not finding one at list (MSRP) price, but if you go to one of those ultra posh Uber elite stores, they MIGHT have one if you throw down a big fat credstick... (see buying more dice) For $32,000, you can get yourself 12 bonus dice... so now it's 18 VS 14.... and chances are you will come out with 1 success...maybe 2 (heck, maybe even 7! or 18!!!)
now we look at the delivery times: (factoring in your $32,000 purchase)
1 success: a week... sorry but the item in store is just a demo model, and you have to wait for shipping (and customs and all that crap).
2 successes: 3.5 days hey, not bad! they offer 3 day shipping on top of the half a day you spent wandering around town looking for the item.. or online
7 successes: 1 day!!! holy crap!!! next day shipping! That store ROCKS!!!
18 Successes: 9 hours!! You smooth talker you! you convinced the sales staff to sell you Richard Villiers back ordered unit! And all it took was a smile, and song and a dance (not to mention travel time, talking time, etc)
this is an interesting quote for you... a little more food for you thought processes.....
SR 5 page 416
Of course, standard goods can also be purchased on
the black market to avoid traceability, but the gamemaster
may decide that the latest copy of Miracle Shooter is
more expensive with the digital serial numbers filed off
and apply a surcharge for your paranoia.
Or, you COULD just look at the bold face int he second to last quote... and use some common sense. (which seems to have disappeared from many people in the 21st century.... I blame the internetz!!)
