The Art of Simplicity: Why Basic Enemies Make Better Games

What if the key to your indie game’s success wasn’t hyper-detailed dragons, but cleverly reskinned slimes? AAA games boast enemy rosters costing thousands per character. But compelling gameplay can come from a single, well-designed slime. Over-reliance on complex, unique enemy design can lead to feature creep and detract from core gameplay. It’s time to champion a resource-conscious approach, celebrating the power of simple, well-integrated enemies that serve clear functions. For indie developers with limited resources, prioritizing functional, well-integrated enemy design over complex, unique designs is more effective.

The Trap of Uniqueness

The desire to create “unique” enemies is a common pitfall for indie developers. It’s tempting to dream up elaborate mechanics and behaviors, but these can be difficult to implement, balance, and, most importantly, teach to the player. Complex enemies often require extensive art, animation, and programming resources, diverting attention from other crucial aspects of the game.

Function Over Form

Function is paramount.

Simple enemy design allows indie devs to focus on core gameplay. Prioritize function over elaborate backstories. Enemies should fulfill clear roles within the game’s core loops. Think about what challenges you want the player to overcome:

• A fast enemy to force movement.
• A ranged enemy to require cover.
• A heavily armored enemy to encourage strategic targeting.

By focusing on these functional roles, you can design enemies that enhance the gameplay experience without overwhelming your resources.

The Power of Reskinning (Done Right)

Don’t underestimate the power of reskinning. Reusing enemy models with slight variations in stats, behavior, or abilities can create depth and variety without requiring massive art or programming investments. Developers can achieve effective reskinning through simple techniques such as using color palettes to differentiate enemy types, designing enemies with modular components that can be swapped, and creating slight variations in existing models.

Consider different elemental types of the same enemy. A basic skeleton can be reskinned as a fire skeleton (deals fire damage), an ice skeleton (slows the player), or a poison skeleton (applies a damage-over-time effect). These variations add tactical layers to combat without demanding entirely new assets. Consider a basic robot enemy. By swapping out different weapon attachments (a laser, a missile launcher, a melee blade) and applying different paint jobs, you can create distinct enemy types with varying behaviors without creating entirely new models.

Integration is Key

The true potential of simple enemies lies in their integration with level design, combat mechanics, and player abilities. A simple enemy in a well-designed environment can be far more engaging than a complex enemy in a bland one. Think about how enemies interact with the environment and how the player can use the environment to their advantage.

A basic melee enemy in a narrow corridor forces a player to choose between a risky head-on attack or a slower, tactical retreat to create space. A ranged enemy becomes more challenging when positioned on a high platform, requiring the player to find a way to flank or eliminate them from a distance. A basic slime enemy, when placed near an environmental hazard like a pit of lava, can be strategically knocked into it by the player using a simple push ability, creating a satisfying and efficient solution.

Examples in Gaming

Many successful games demonstrate the effectiveness of simple enemy design:

• The Legend of Zelda: Ocarina of Time: The Bokoblins (and their many variants) in Ocarina of Time serve different functions depending on their weapons and environment, despite their relatively simple AI. Some carry shields, requiring players to attack from the side or behind, while others throw rocks from a distance. Key takeaway: Indie devs should focus on level design and enemy placement to create diverse combat scenarios without complex AI.
• Minecraft: The iconic Creeper is a simple enemy with a single, devastating behavior (exploding), but its impact on gameplay is significant. Its simplicity creates emergent gameplay and tension. The simplicity allows new players to quickly learn the core gameplay loop. Key takeaway: Indie devs should remember that a single, impactful behavior, combined with environmental factors (like the player’s base), can define an enemy and create emergent gameplay.
• Dark Souls: Hollows, the most basic enemy, are dangerous in groups and teach players the importance of spacing and timing. This exemplifies how basic enemies can effectively teach core game mechanics. These enemies provide low-stakes opportunities to learn core game mechanics. Key takeaway: Even the weakest enemy can reinforce core mechanics; consider how simple enemy encounters can teach players about spacing, timing, and resource management in your game.
• FTL: Faster Than Light: The various enemy ship types in FTL utilize simple attack patterns and abilities in unique combinations to create tactical challenges for the player. They provide emergent complexity and challenge without relying on advanced AI. The game emphasizes strategic resource management. Key takeaway: FTL highlights the power of combining simple elements (attack patterns, abilities, ship layouts) for emergent gameplay. Indie devs can use this approach to create challenging encounters without complex AI.
• Space Invaders: The enemies move back and forth. The challenge comes from their increasing speed, numbers, and the player’s limited movement, demonstrating how simple behavior can create addictive gameplay by emphasizing player skill and resourcefulness within tight constraints. Key takeaway: Focus on core gameplay and increasing difficulty through simple means (speed, numbers) to create addictive gameplay loops in your indie titles.

The ROI of Simplicity

Simpler enemy designs offer a significant return on investment (ROI). Reduced development time, faster iteration cycles, and easier balancing all contribute to a more efficient development process. But one specific technical challenge indie developers face when implementing even seemingly simple enemy AI is pathfinding. NavMesh solutions can be resource-intensive to generate and update, especially in dynamic environments.

Simplicity is key.

Instead of a full NavMesh, use A* pathfinding with a simplified heuristic that only considers distance to the player, ignoring minor obstacles. This dramatically reduces the computational cost. Limit your behavior trees to a maximum of 3-4 states (e.g., ‘Patrol,’ ‘Chase,’ ‘Attack,’ ‘Flee’). This simplifies the AI logic and reduces processing load. Implement a basic patrol point system where enemies move between 3-5 pre-set locations. Use a simple random number generator to determine the next patrol point, adding a small element of unpredictability. By focusing on core functionality, developers can allocate resources to other critical areas, such as level design or player abilities, ultimately enhancing the overall quality of the game.

Conclusion

In conclusion, don’t fall into the trap of complex enemy design. Embrace the power of simplicity. By focusing on function, integration, and smart reskinning, you can create engaging and challenging gameplay experiences without breaking the bank. Remember, a well-designed game is more than the sum of its parts. Before your next sprint, challenge yourself to remove 50% of the lines of code from your most complex enemy AI. Can you achieve equal or greater player engagement with simpler logic and smarter level design?
