Region Creatures Timeline
Andrew: There was actually a ton of thought that went into the creatures that spawn in each region, at each spot on the timeline.
Andrew: Will had actually put together an entire illustrated timeline chart for every creature
in the game, showing their presence, evolution, and extinction events across the game's history.
Andrew: As well as another long document explaining the origins, food chains, migration
patterns, preferences, and other attributes of each creature's species over time.
Andrew: All of these considerations were factored into which creatures to include and exclude in each region for each character.
Andrew: Will also wrote a region creature density analyzing script, which he used to balance out creature spawns in each
region to keep difficulty levels consistent, and creature densities appropriate based on the global population decay.
