Hi there,

I've been intrigued by the QREBS rules in T5 especially as they're easily transportable to, say, Mongoose rules or classic Traveller.

I've been wondering about a mechanism to link QREBS to the price of (new) equipment etc although I'm aware that referees might not want to give players or PCs *direct* information on the QREBS values. (Although there is a rule about players spending an hour examining an item having a bit of an idea about the condition of the object).

I wondered if this might be a mechanism and what anyone thought of it (and have I explained it clearly enough?):

A rule of thumb might be +5% cost for every level of Quality over 5; -5% for every level under 5. Similar variations could be used for the reliability, ease-of-use, burden and safety. Perhaps an additional +/- 1% per QREBS point for each value.

Thus an item with QREBS = 8 0 -1 0 +3 would mean an additional 17% on a ‘book’ price (+ 3 x 5% - 1 x 1% + 3 x 1%).

Or QREBS = 3 -1 0 +2 0 would mean -13% (- 2 x5% - 1 x1% - 2 x1%). (Don’t forget that burden is reversed).

So in a showroom their might be three air/rafts that cost Cr275,000 in the Mongoose Core Rulebook (p.103) and might be:

A: QREBS A -1 +3 -1 0 and cost Cr352,000

B: QREBS 5 +2 +1 -5 -1 and cost Cr294,250

C: QREBS 1 -1 0 +2 -1 and cost Cr209,000

The idea being to give PCs more choice rather than just "you buy an air/raft, it's Cr275,000" (which I'm sure no referee worth their salt would do!). And to introduce the element of risk vs cost that QREBS must be there for. Yes, it's cheaper to buy C but will you spend more of you time under the bonnet (USese: hood) than you do flying the thing?

Thoughts? (have I done my math right?)
