The "exclusive" language pack essentially acts as a bridge for modern-day players to experience this lore-heavy narrative in their own native languages, even if the characters themselves are technically meant to be speaking a "default" tongue.
While "rune exclusive" refers to a scene release, the official remaster includes its own set of legitimate exclusive content. All pre-order and special edition bonuses from the original game have been bundled into the remaster. The Horizon Zero Dawn Remastered includes the full The Frozen Wilds expansion, as well as several in-game items:
The remastered version supports a wide variety of languages for both audio and text, including: Full Audio & Text
The Remastered edition includes significant accessibility and technical updates for various languages: Comprehensive Audio & Text
However, to keep the initial download size manageable, the RUNE release only included English VO (Voice-Over) by default. For players who wanted to experience the game in other languages, the group later released a separate, optional download called *"Horizon.Zero.Dawn.Remastered.Language.Pack-RUNE".
