My d20 Star Wars group just (over the past two sessions) concluded a major bacta deal.
We - a group of 8 or so 4th- / 5th-level characters - raked in approximately 3 million credits.
Of course, we're working for the Republic, and it's technically their money, but it's ours to do with as we please, at least until the accounting gets done at the end of the mission.
So, what have we done with this huge windfall? We spent 20K credits apiece on clothes and accessories for two major parties thrown by a system noble who's suspected of having Separatist ties. We spent thousands on hotel rooms. We bought lavish host gifts. We purchased, programmed, and powered up two engineering droids and a loading / defense droid for our ship (which is also on loan from the Republic).
We're right now considering what modifications to make to our light freighter. Notice that we're considering modifications to an existing (and somewhat subpar) craft, and not "Buy our own merchant fleet" which we could conceivably do. Our mission doesn't really allow for it, though - and we like the ship we're currently in. The Blind Luck has character - and it's gotten us out of two near-run situations in one piece (an encounter with a Interdictor-style cruiser and the siege of Procopeia by Separatist forces).
In short, having the money for once in my RPG life to no-kidding act rich has been a breath of fresh air and a great time has been had by all.
