I got one I remember. Its from Fallout 2.
I can't recall the town. Not Reno, Not Vault City, Maybe Klammath. Its definatly near the beginning.
Anyway, when you get to town thers a bar/casino just down from the entrance and to the right (on the screen). They have two working crap tables in there. Save your game. Play craps with maximum bets and odds on your point. If you win, you get a whole lot of money, if you loose, reload. What I liked about this is you really are playing craps, so its kind fun while your stacking up money. Oh ya, save after you win by excusing yourself from the table and then saving the game. Don't want to loose any of those winnings.
Also, this may not be what your looking for if your too lazy, cause you'll have to reload a few times to save up enough money. And you have to place your bets from scratch after you crap out.
