John Carmack and John Romero reunited to talk DOOM on its 30th Anniversary
DOOM’s 30th anniversary reunion interview has prompted reflections on how its fast, readable combat, simple enemy AI, and mechanics like monster infighting prioritized player fun over technical sophistication. Commenters highlight the huge impact of id Software’s decision to open‑source its engines on game preservation, ports, and modding communities, and contrast the rapid innovation of the 1990s PC era with today’s more incremental advances. Many also point to DOOM’s enduring mod scene and its influence on networking careers and game development culture as evidence of its lasting legacy.
Anniversary Conversation & Design Philosophy
- Listeners enjoyed hearing the original developers discuss their work 30 years later with clear passion.
- A key theme: better or more realistic enemy AI does not inherently make games more fun.
- Examples: ultra-fast drones or enemies executing complex unseen plans can feel unfair; players prefer encounters that highlight their own actions.
- “Big and dumb” enemies, predictable behaviors, and features like monster infighting are praised for depth and fun at relatively low implementation cost.
- Some note dislike of “cheating” AI at high difficulty (perfect aim, unfair knowledge).
AI, State Machines, and Perceived Intelligence
- Many commenters argue most game AI, historically and now, is some form of state machine.
- Determinism is valued for debugging and reproducibility.
- One popular shooter is cited for feeling smart largely via contextual voice lines and feedback, not complex logic.
Open Sourcing & Engine Legacy
- The longevity of the game is widely attributed to engine source releases and mod-friendliness.
- Commenters lament that many beloved games/engines remain closed, citing middleware and licensing as major blockers.
- There is discussion of community reimplementations and ports of later engines that partially fill the gap.
- Some argue open source’s main impact is on developer curiosity and niche ports; others highlight vibrant source-port and mod scenes as substantial.
Modding Communities & Comparisons
- The game’s modding ecosystem is seen as unusually large and long-lived, helped by simple mapping tools and approachable tech.
- Comparisons are made with other heavily modded titles (other 90s shooters, immersive sims, RPGs, strategy games, and modern sandbox games).
- Several note that increasing engine complexity (post–early 2000s) has raised the bar for hobbyist modding, with a few big exceptions.
Historical Context & Personal Impact
- Commenters reflect on the rapid innovation from early 90s to early 2000s FPS and physics-driven games, contrasting it with more incremental recent progress.
- Multiple anecdotes illustrate the game’s cultural impact: LAN adoption, workplace distraction, personal visits to the studio, and even helping some cope with intense religious fear.
