Define worlds in XML and watch them come alive in a simulation with flowing water, seasons, climate-driven vegetation, and early terraforming.
Schema
SteamSchema is a simulation-driven game engine where worlds, rules, and interactions are defined using XML schemas.
Instead of hand-building levels, you describe a world and Schema renders them into a playable simulation.
Featuring procedural block-based worlds, height maps, and text-driven RPG mechanics, Schema is designed for experimentation, systemic gameplay, and emergent behavior rather than scripted experiences.
