I ran a War Rocket game yesterday using dials from Dial Dude http://www.the-d-d.net/ to track the number of shots on targeted spaceships. I didn’t have to worry about d20s rolling around, having enough tokens to signify all the points of firepower engaged or to clean up all those tokens.
A dial consists of 2 magnetic discs. One is numbered from 1 to 10 and the other is black with a “pie slice” cut out. I merely turn the cut out die to expose the correct number of weapon factors targeted on the rocketship and I’m good to go.
