Obviously this will be something that varies between groups and Gm's and games themselves, but there seems to be a theme of the party constantly needing money/getting small amounts in EOTE. However in beyond the rim and jewel of javin there are ways to earn really large sums of money. I think you'd be hard pressed to find a group that wouldn't pursue these leads to get as much as possible. And for skilled players or even just skilled characters who can roll a lot of dice they can attain these goals without really throwing the adventure off track.
There is a few issues with selling off the Jewel (not even starting on the fact that the party could keep the auction money with good rolls and luck) and selling the bars from beyond the rim, but I don't feel like they shouldn't get there money's worth as these items have one, listed values in the books, even altering these figures still gives decent amounts, and two, they have if you run the adventure by the book earned them fair and square by having the dice on there side or good rollplaying etc etc.
I still think that the problems of acquiring such items should be present (bounty hunters, other interested parties you name it) but not in ways the significantly devalue the items acquired. I also like the idea of cash sinks but you can really only own so many ships or whatever else you can think of. Seeing as it's up to the Gm to control the balance of the game to the way they think is fair I was wondering how other people see this. I think my opinion is that if they earnt it make it hard but give them it in the end. What do you guys do and do you think that the game is meant to be played in this way or do you think this kind of thing is not really the shenanigans pc's should be doing.
