Standard RPG System
The Standard RPG System (SRS for short) is the role-playing game system used in Alshard, Alshard Gaia and Tenra War. It was announced that the fourth SRS game Kaze no Stigma RPG will be released soon. Standard RPG System is available under an open content license for non-commercial uses.
Core mechanic
Standard RPG System uses only 6-sided dice. To determine whether the action is successful or not the player rolls only 2d6, if the total of the dice rolled by the player and ability/class adjustments is more than or equal to difficulty score the action succeeds. To determine damage the player rolls a number of 6-sided dice. The number of dice that are rolled increases with various class abilities.
Players choose up to three character classes during character creation - for example, fighter/fighter/fighter (a 3rd-level fighter), valkyrie/valkyrie/scout (a 2nd-level valkyrie/1st-level scout), or black magician/white mage/wizard (a 1st-level black magician/1st-level white mage/1st-level wizard).
There are 6 attributes, Tairyoku (Strength), Hansya (Reflex), Chikaku (Perception), Richi (Reason), Ishi (Will) and Kouun (Luck). In Tenra War, Tenka (All under heaven, it represents social ability) is present instead of Kooun (Luck). The characters' attributes are decided by the selection of classes almost automatically. Attribute scores also determine several 8 combat ability scores.
In Alshard and Alshard Gaia, characters possess supreme divine powers according to their classes. For example, fighters possess the power of 'Thor', which adds extra damage to damage rolls, while white mages possess the power of 'Idun', which can raise the dead. Supreme divine powers are named Kago (加護, Kago? lit. divine protection), and work much like hero points. Each character can use Kago three times every a session, according to three classes was chosen during character creation.
Scene System
The game session is divided into 4 phases: opening phase, middle phase, climax phase and ending phase. In opening phase, player characters (PCs) get into the incident with each motivation such as business, adventure, curiosity and romantic feeling for the heroine. In middle phase, PCs get together. And they fight against creatures and research the incident. In climax phase, boss enemy appears as the arch-foe against PCs. Ending phase is the phase for epilogue. Each phase is also divided into several scenes. The Game Master(GM) choose scene player as the scene's protagonist. If GM allow and the player succeed in Appear roll, other PCs can appear on the scene.
