Echoes of Starfall
Narrative RPGA narrative RPG built around memory and choice
Every non-player character has their own memories, loyalties and emotional state. They shift their attitude, the story branches they open up and the quests they offer based on how you have acted and what you have said. The game is the first full-scale application of the company's Character Memory System.
A management sim driven by staff personalities and customer relationships
Players balance shift scheduling, menu design and customer loyalty. Each staff member has a distinct personality and responds to how they are treated, while customers remember every visit and decide whether to come back. The game supports offline play and has no mandatory daily tasks.
