In regards to the dice game, to make it more of a way to get some small amount of money, maybe give a person 3X or 2X their money when they roll a 3, that way the gambling won't be AS much of a money hole, as well as making those quests a little more obtainable.
It'd be cool if you added junk to fishing: Black bubbles appear and if you reel it in, it's something like an old boot or garbage and you lose exp/money.
Love this game, my only issues is when there is a zombie outbreak, my game starts to reallllly laaag and then i have no idea if im dying or not because it takes 10 sec for my last button to regiseter...
