Excuse me but what exactly are you auditing?  

If someone is auditing games for the term RPI, then they are doing players a disservice.  They are no longer auditing, they are involved in subjective game review.  

It's especially annoying because apparently only a handful a people are privy to the EXACT definition that's being audited against then.  And apparently that definition isn't even consistent based on the various RPI muds web pages I've visited.

Now I've asked twice now and so have a few other posters.
Where can I find the definition of RPI?  

Do you know when it first appeared on Usenet?
It looks like 1998 to me.  Looks like someone defined it as having multiple currencies and horses and carriages. :-P
