About

Manchego Games

An author-led creative label for modular systems — worldbuilding, tactical play, and emergent storytelling. Frameworks designed to give structure without removing freedom, from drawing maps by hand to commanding soldiers under fire.

Craft, patience, and durable design. Systems that empower people to create.

Jaime Gonzalez Vallejo

Founder of Manchego Games. Originally from La Mancha, Spain. Over thirteen years in the video game industry — first as an Environment Artist, later as an Art Production Manager. Spatial design, environmental storytelling, and structured creative pipelines.

Manchego Games is where I build systems that give structure to creativity — from drawing worlds by hand to simulating the chaos of command under fire.
