koima57: Hmm.. There is that fantastic "Thousand Arms", a PsOne game blending dating sim, RPG and what you are asking, an in-game job.
It follows the story of the son of a blacksmith, which goal is to become the successor and master of his work, with the particularity of being heir of a family of lustful dudes in need of damsels as muses, to get the job done. All through the game you don't make money with your job, but you pay to exercice it at elemental forges to improve it through your swords. Still, an in-game job as the main focus.
I dont and won't condone any pyracy, but I have the game in its original CD case (2 discs) and often play the ISO through pc emulator, or an eboot for my PSP and.. What a game!!
Thanks a lot for the suggestion, I'll have to check this out.
