The One-Roll Engine ( ORE for short ) is a cube system devised by Greg Stolze for pen & paper role-playing games . It originally served as the basis for the superhero role-playing game Godlike (Arc Dream Publishing, 2002). Since then, it has been further developed in several subsidiary systems , e.g. adapted for the contemporary scenario of Wild Talents (2nd edition 2006, Cubicle7 & Arc Dream Publishing), for horror scenarios ( Nemesis, Arc Dream Publishing, 2006) and, since 2007, also for classic fantasy scenarios ( Reign - A Game of Lords and Leaders, Schroedingers Cat Press, 2007) or simplified for superhero scenarios ( Better Angels , Arc Dream Publishing, 2013) and ( Monsters and Other Childish Things , Arc Dream Publishing, 2014). The rules and regulations based on this system have been continuously expanded through supplementary publications since their appearance.
ORE is new because the players can map the success of an intended action, their initiative in comparison to fellow players and non-player characters , as well as their hit zones and damage caused within a single throw of dice . Compared to other systems, such as the most popular in German-speaking countries ( Das Schwarze Auge ) or the d20 , which is by far the most popular in English-speaking countries , the gameplay is radically simplified.
Game mechanism
ORE uses dice amounts ( Engl. Dice pool) to be determined by ten-game litters (W10) to all the variables of player actions, including the success. For this purpose which are Päsche (pairs, triplets, quadruplets ... equal to each other as an eye number) is interpreted within a roll. A double signifies the success of an intended action. The attribute value and the corresponding skill value of an RPG character are added together to determine the size of the dice set. This success is determined by its width (the number of identical sides of the dice within one throw) and by its height (the number / number of dice on the sides). This is written in short as "width x height" (three of a kind of 5s: 3x5).
While the height of a double determines the quality of a success, the width indicates its speed or required duration. In combat situations, the width of a double also determines the amount of damage; the height, however, also the hit zone (1/2 for left / right leg; 3–4 / 5–6 for left / right arm; 7–9 for the torso and 10 for the head). A distinction is made between simply reversible shock damage and difficultly reversible killing damage. In some situations, the unpaired remaining cubes are also important.
Various aspects of the game mechanics, according to which competing characters can set off (break) individual success dice against each other (gobble dice), or the game master can assign success difficulties in height and / or width to a sample, make it difficult to predict success chances.
In special cases (special dice, differ in child systems) a player may influence the result of one or more dice:
- Hard die - always gives a height of 10
- Master's dice, changeling dice, trump dice - the value of the amount is determined by a player according to special rules after the rest of the dice have been thrown
- Expert die - value of the height is determined by a player before the remainder of the dice is rolled.
The individual subsidiary rules still differ in relation to the ORE cube system:
- whether several of these special cubes are permitted within a set of cubes,
- in which framework a player must adhere to when deciding on special dice,
- whether a throw with guaranteed success (i.e. number of dice exceeding 10 dice) is permitted,
- whether and in what way special dice or excess dice (beyond such a quantity restriction of 10) can compensate for situation-related disadvantages for role-playing characters.
