i'm not saying that gil values won't be the same, but this is one of the cases where perception will be reality. if people freak out when they see their gil get lower they will become more stingy spending it even though it has the same monetary value.
i remember a few years ago my wife and i went to vegas(either 2005 or 2006). she came by and i was playing craps and had been having a decent run at things. i had all of the bars in front of me filled of chips. she walked back by a few hours later and i was down to the top bar full and only part of the second bar with a few chips. she started yelling "we need to go before you lose all your chips". i looked at her crazy, but was sleepy so left with her anyways.
later we got to the room and i asked her what she was talking about. she was like earlier "you had all 5 bars full of chips, but later you were almost out of chips". i had to laugh at that and responded "yeah, but earlier it was full of $1 and $5 chips, but when you came back those were all $100 and $5 chips". even though i had picked up over $13,000 in cash that night playing craps she thought i was about to go broke because she just saw the numbers of chips get lower and paid no attention to the value those chips had.
this is what i mean by perception is reality in most cases.
