Forge Engine

The goal is that a new game idea can start on a Friday and be playable by Sunday, backed by systems that already exist.

Forge is built as layers of removable plugins over a lightweight core that owns lifecycle, configuration, assets, diagnostics, serialization, saves, and scenes. Everything else — physics, AI, audio, UI, terrain, menus, input — is optional. Entities, abilities, materials, and items are data-defined, and much of it stays tunable while the app runs.

This one is purely for fun.
