Why RPG Towns Cost Four Times More Than Dungeons, According to Josh Sawyer

Understanding the Cost Gap Between Towns and Dungeons

When developers talk about budgeting for a role‑playing game, the term "dungeon" often evokes images of cramped corridors, monsters, and treasure. A town, by contrast, suggests bustling streets, markets, and a sense of community. Josh Sawyer, lead designer at Obsidian Entertainment, recently highlighted a striking statistic: a town can cost roughly four times more per square foot than a dungeon. The reason is not fantasy magic, but the very real concept of zoning.

Zoning Laws in the Real World and Their Virtual Echo

In municipal planning, zoning determines what can be built where, how tall a structure may be, and how much space must be allocated for public use. These regulations increase land acquisition costs, require infrastructure, and impose design constraints. When game designers translate these principles into a virtual setting, the same cost multipliers appear.

For example, a city block in a real city often includes setbacks, green space requirements, and utility corridors. In a game, each of those elements consumes polygon budget, texture memory, and development time. The result is a higher per‑square‑foot expense compared with a simple dungeon layout that lacks such constraints.

The Influence of Zoning on RPG City Design

Obsidian’s own development pipeline incorporates zoning considerations early in the design phase. By treating each district as a separate zoning zone, the team can estimate costs more accurately. This approach mirrors practices used by urban planners and is documented in resources such as the U.S. Department of Housing and Urban Development guidelines.

Key Zoning Factors That Drive Up Costs

• Land Use Mix: Combining residential, commercial, and civic spaces requires diverse assets.
• Infrastructure Requirements: Roads, water lines, and power grids add hidden development hours.
• Regulatory Buffers: Setbacks and height limits force designers to allocate extra space.
• Public Amenities: Parks, plazas, and statues enhance immersion but increase asset count.

Josh Sawyer’s Perspective on Budget Allocation

In a recent interview, Sawyer explained that the four‑fold cost increase is not a flaw but a design choice. "If you want a living city that feels real, you have to pay for the complexity," he said. He compared the budgeting process to constructing a real‑world neighborhood, where each square foot carries a price tag due to zoning compliance.

Sawyer also noted that the expense is justified by player expectations. Modern gamers expect detailed, navigable towns that react to their actions. This expectation drives studios to invest more resources into city building, echoing findings from a study on game economics published by ACM.

Practical Steps for Managing City Costs

1. Define zoning zones early and assign a cost multiplier to each.
2. Reuse modular assets across districts to reduce unique asset creation.
3. Prioritize player‑visible areas; hide complexity in background zones.
4. Leverage procedural generation for streets and building footprints.
5. Conduct regular cost audits to keep the budget aligned with design goals.

Balancing Player Immersion and Development Resources

Players often judge a game’s quality by the depth of its world. A well‑designed town can become a character in its own right, offering quests, lore, and social interaction. However, the higher cost per square foot means studios must balance ambition with feasibility.

One strategy is to focus on narrative hotspots. By concentrating detailed design on areas where the story unfolds, developers can allocate resources where they matter most. This technique is highlighted in a GDC talk on city design that discusses efficient use of development time.

Case Study: Obsidian’s Use of Zoning in a Recent RPG

In the latest installment of Obsidian’s flagship series, the development team mapped out the capital city using a three‑layer zoning model: commercial core, residential outskirts, and civic district. Each layer received a distinct budget, with the commercial core receiving the highest allocation due to its visual prominence.

The result was a city that felt alive without exceeding the overall project budget. By treating zoning as a budgeting tool, the team avoided the pitfall of over‑building low‑impact areas.

Lessons for Indie Developers and Modders

Even small teams can apply zoning principles. By creating a simple spreadsheet that assigns cost values to different zone types, indie developers can predict how expanding a town will affect their schedule and finances.

Modders also benefit from understanding these concepts. When adding a new settlement to an existing game, respecting the original zoning logic helps maintain visual coherence and performance stability.

Quick Reference Checklist

• Identify zone categories (commercial, residential, civic).
• Assign realistic cost multipliers based on asset complexity.
• Map out infrastructure needs before building assets.
• Use modular and procedural tools to reduce repetitive work.
• Review budget impact after each major addition.

By integrating zoning awareness into the early stages of design, developers can create richer towns without unexpected overruns. As Josh Sawyer demonstrated, the four‑fold cost increase is a predictable outcome of striving for realism, and it can be managed with disciplined planning.
