Cup & Coin trick:
At the beggining of the game when you go to Rockland there will be a old 
woman who will let you play a cup & coin game where you have to guess 
which cup the coin is in after her whipping them around.
1)Save before talking to her.
2)Talk to her.
3)Bet 100 (which is very easy), until you get 1000 gp.
4)Bet 1000, and pick the right cup, bet 1000 again and pick the middle one, 
then save, and come back and bet 1000 and pick the right one again and then 
pick the middle again and save.
5) Keep on doing the pattern Right, Middle, save game, right, middle, save 
game, until you have 10,000 gp and go back there (after saving), and the 
pattern right, middle, save game will still work. (Too bad there wasn't 100,000 and 1,000,000)
