But Liar's dice isn't really realistic to script opponents for, which means you'd have to wait until another person was around. The computer, after all, knows PRECISELY how many of each value turn up.
Edit: As an addendum, if you have ideas for mini-games, build them as a .mod or .erf, and provide them wholesale to the design team. Worst thing that happens, they don't include them, and you have a mini-game of your own to play with friends. Best thing that happens, they decide, because of the time you've saved them, to include the new game. You are surrounded by yesmen and hangers-on, desperate for a taste of the fame you acheive. Women (or men) swoon before you, and national holidays are declared in your honour.
(Well, at least the game will be included.)
