Sprawl — High-Level Design

Sprawl is a blockchain strategy game built around contested expansion, resource economies, and continuous taxes.

At a glance:

• Hex map with unique, algorithmic tile seeds
• Land sold continuously through auctions on map edges
• Every tile has taxes and yields
• Users mine and discover resources by submitting PoW-like proofs
• Neighbourhood-based taxes create local trade loops
• Optional military layers create tactical conflict

The key design direction is that gameplay remains mostly economic and networked, with military as a meaningful but optional amplifier.

Core loop

1. Buy or bid for frontier tiles.
2. Set self-assessed tile value.
3. Pay recurring taxes in valid resource sets.
4. Discover resources on tiles.
5. Trade resources in an open economy.
6. Grow outward with new land and better position.

What we are not trying to ship first

• Complex probabilistic combat
• Hard strategic bottlenecks that punish newcomers
• Huge unit trees before core economy is stable
