As we play with random events, bouncing asteroids and the like there are many RPG dices on the x wing table. One of them.is my first D12 dice, purchased in 1985. 30 years...it is more valuable to me than a Raider. Fantasy, modern, sci fi RPGs, Random selection, few wargames use a D12 but some do.
30 years rolling, more a friend than a tool. Just like a battered R2 D2 unit...
