Gamers who have played pen and paper RPGs might recall that every Game Master seems to enforce his or her own set of sub-rules, for example whether or not to require that characters must eat during the adventure and therefore must carry a suitable supply of rations with them. With Book II, we've implemented a similar system of allowing a customizable set of rules that can be chosen before the start of each game. Each rule imposes a unique set of restrictions, allowing the players to make the adventure as challenging as they prefer. The tradeoff is that the more demanding they make it, the more the system will reward them with bonuses to the quality of random loot, additional experience points, and a higher rank at the end.​
