## Summary
Crown of Hispania, developed by Regalis Studio and published by indie.io, is a grand strategy game set in the Iberian Peninsula during the early 1000s. The game covers the period following the Moorish conquest and the subsequent Christian Reconquista. Players manage provinces through dual urban and rural systems, issue policies, build infrastructure, and navigate dynastic politics including marriage alliances and warfare. The game runs on Linux and Steam Deck via Proton. A Boiling Steam review notes that while the game has strategic depth, its current interface makes it difficult to locate specific actions, and the tutorial is described as shallow with some hard-locking issues reported.

## What Crown of Hispania offers on Linux
- **Proton compatibility:** The game runs on Linux and Steam Deck through Valve's Proton compatibility layer, with no native Linux build mentioned.
- **Dual-layer province management:** Each province has separate urban center and countryside aspects, with distinct policies for migration between them and infrastructure construction including farms, workshops, and churches.
- **Dynastic systems:** Marriage alliances can transfer territory between realms, as demonstrated when the reviewer inherited Castile and Leon through familial connections after a battle death.
- **Interface limitations:** Menu navigation is described as difficult, with inconsistent availability of diplomatic options, unclear conditions for interactions, and no ability to bundle or counteroffer diplomatic proposals.
- **Faction asymmetry:** Playable factions vary significantly in starting strength, with major kingdoms like Castile fielding armies of ten thousand while smaller factions like the Maghrawa struggle to reach one thousand troops without conscription.

## Why it matters
The release adds another verified Proton title to the Linux gaming catalog, specifically in the underserved grand strategy genre where Paradox Interactive titles dominate. For Steam Deck users, it provides a portable entry point to historical strategy gaming without native port requirements. The review's detailed compatibility assessment helps set expectations for Proton performance and UI limitations that may affect controller-based play.
