OpenRA

Original Article ↗ Hacker News Discussion ↗

OpenRA is an open-source engine that recreates classic Command & Conquer–style real-time strategy games like Red Alert for modern systems, earning praise for improved balance, quality-of-life features, and active cross-platform multiplayer. Commenters trade tips on AI opponents, debate what “fair” RTS AI should look like, and explore how LLMs and custom scripting could power new kinds of computer players. The thread also highlights related fan projects, browser ports, and remasters, alongside strong nostalgia for LAN play and modding of the original titles.

AI, Bots & “Intelligence”

  • Many find the built‑in AI hard and note that RTS AIs commonly “cheat” via resource bonuses, build-time multipliers and full map vision.
  • Others point out examples of “fair” AIs and stress that in classic CS terms this still counts as AI; the goal is plausible, challenging opponents, not superhuman play.
  • StarCraft bots via BWAPI and systems like AlphaStar are cited as strong but still below pro players (under fair constraints).
  • LLMs are seen as excellent tools for authoring RTS AI scripts and heuristics, but too slow and wasteful for real‑time control.
  • Some experiment with LLM-generated tournaments between AI scripts; newer models can outperform their human game designers.

Gameplay, Balance & Technical Choices

  • Several players feel OpenRA is better balanced and more fun than the original, with specific examples (e.g., artillery vs tesla coils) showing improved counterplay.
  • Others like the original’s imbalances and “just build Tesla Coils” style.
  • One fork claims much better AI behavior, pathfinding, performance (on newer .NET), and partial Tiberian Sun support, but its maintainer had a poor experience contributing upstream.
  • The save/load system replays the entire match to restore state. This is praised as technically impressive but causes extreme load times for very long, large games.

Ports, Related Projects & Assets

  • Users ask about browser versions; links are shared for a browser OpenRA frontend and a RA2-in-browser project (Chrono Divide), which is described as remarkably advanced.
  • Other open RTS/engine remakes mentioned: Beyond All Reason, 0 A.D., remakes of Heroes of Might and Magic II, and Caesar III forks (Julius/Augustus).
  • Some hit a “wall” needing original assets; others note EA released C&C/RA as free downloads.

Community, Ecosystem & Nostalgia

  • Many express strong nostalgia: LAN/serial/IPX play, modding via INI edits, iconic music used for coding, and personal stories of unlikely RA experts.
  • Reports on the online community are mixed: some praise the active player base; others describe toxicity, racism, and trolling and ask if moderation has improved.
  • There is frustration that Tiberian Sun/RA2 support is still incomplete, especially from someone who backed an old crowdfunding effort.
  • EA is criticized for “ruining” the franchise but also credited for tolerating or even open‑sourcing older titles.
