The one that we've used most in my games, the content is specific to my group's Homebrew World and AD&D game, so I won't paste the actual code here, but just explain the idea. It's 2 rollable tables, we output the text results of both into the Chat Room with a single macro button, and it generates a True or False, Vision or Dream sequence, which contains creative writing submitted by all the Players in the group. One character has VISIONS, this is specific to our game, the character just has flashbacks and foresight, in the game. 2 rollable tables determine what the vision is, and he "rolls" one new vision each week, when we play, and it usually changes the game story quite a bit, and sometimes effectively makes a new roleplaying scenario or encounter pops up instantly. In our game the first table is the TRUTH TABLE and has 20 results (such as True, False, Unavoidably True, Might Come True, Can Never Come True, etc). The second table is the VISION (dreams, written in creative writing, about 1 sentence each) which all the Players contributed 10 dreams each, making 60 dreams. 20x60 = there are 1200 possible resulting visions for the character! We never know what might happen. The same idea could be done for Wild Magic, or Fortune Telling, or Mixing Potions, or Treasure Finds, anything with a random text result. Example TABLE 1 x TABLE 2 Huge Pile Of Gold Pieces Only 1 or 2 Gems Some Worthless Weapons Couple of neat tips from how we used RT's, 1. you can have 2 rollable tables and if the results are combined in some way (such as True/False table, and Vision table... Or the example above with Quantities, and Items). That way you have a multiplication effect on the possible results, which can bring a lot of unexpected randomness. 2. Second tip: Ask all your Players to submit 5 or 10 "results" each for a rollable table, that way it is a randomized selection of participation/input from everyone in the group, each time it is rolled. People get excited to see if one of their suggestions is the actual roll for that day. This kind of gameplay isn't written into the rules of D&D or most games, but, you can actually do this in almost any RPG. It's up to the Game Master to decide to ask your Players to contribute writings, which the GM can place into a Rollable Table and run it back at the Players for part of the game. For example you could ask your Players "Everyone submit a list of 5 wild magic bursts that you want to see happen in the game" . Or you could have your players submit monsters or animal types for Table 2, and GM could make Table 1 say things like "Giant" or "Miniature", so you roll things like Giant Chicken (where one of the Players chose to put "Chicken" on the list).
