System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

An Example of Play

To further clarify what really goes on during an AD&D game, read the following example. This is typical of the sort of action that occurs during a playing session. Shortly before this example begins, three player characters fought a skirmish with a wererat (a creature similar to a werewolf but which becomes an enormous rat instead of a wolf). The wererat was wounded and fled down a tunnel. The characters are in pursuit. The group includes two fighters and a cleric.

Fighter 1 is the group's leader.
