The 100-sided Dice System

The system which uses a 100-sided dice or, more probably, two 10-sided dices where one is chosen for the units and the other for the ten or so, is used in two circumstances  : bonus system and percentage system. We will criticize here the bonus system. 

Our Opinion

Advantages :

The bonus system provides the Game Masters with the greatest amplitude and is perfect for most Roleplaying Games. It's flexibility is unequalled because the Game Masters can define any difficulty level  he wants. The "Opened and Added System" allows the PC and the NPC to rethrow and add a dice when the first result is greater than 96. This option allows a weak character to succeed against a strong one.

Disadvantages :

Sometimes, Critical Hits and Critical Errors may be catastrophic, but that's a part of the Game and the Game Master is free to suppress any throw that a NPC should roll and which would be mortal for a Player.
