I think something needs to be done about the dice-rolling mechanic itself. Because rolling dice is just plain boring — you have absolutely no influence on the outcome. You need to add some additional activity for the player. For example, the ability to cheat on your roll, but in a way that your opponent doesn’t notice. And during the opponent’s turn, you’d need to keep an eye on them to make sure they’re not cheating, and spot it based on certain tells. Basically, do something so that the dice roll button doesn’t feel like a “next” button — otherwise it ends up feeling like a Windows installer wizard.
