I saw this and seriously was like.. "wait... is this for real...?" And then I was like.. "Wait...! is can use this to help homebrew rules and scenarios for Rivet Wars"! Like to playtest so nothing is unfair, without mistake. Since Rivet Wars basically is RPSLS.. For example, Assign an armor type to Spock for example.. figure your dice rolls and see if it actually "fair"... the uses are really endless between this and Dungeon Roll that just started as well.. crazy stuff. Crazy simple games coming out btw.

I won't even say the "Z" word... o_O
