Steam, alternative Linux à GOG Galaxy

Mis à jour le

Notre avis

Steam can serve as a replacement for GOG Galaxy for most users who want a single launcher for both native Linux titles and Windows games via Proton. It offers a unified library, cloud saves, achievements, friends and chat, and an overlay. However, it does not aggregate purchases from other stores, so if you rely on a multi‑store catalog you will lose that convenience. For gamers who are comfortable buying new titles on Steam and importing existing ones, it is a solid alternative; power users who need a true store‑agnostic hub may still prefer GOG Galaxy or a separate manager.

Ce qui fonctionne pareil

  • Unified game library
  • Friends list and chat
  • Achievements and playtime tracking
  • Cloud‑save synchronization
  • In‑game overlay

Ce qui change

  • Steam does not import purchases from other storefronts; it only shows games you own on Steam or add manually
  • GOG Galaxy offers DRM‑free imports and automatic detection of many non‑Steam Windows games, while Steam requires manual addition for non‑Steam titles
  • Steam’s cloud saves work only for games that support SteamCloud; other Windows games run under Proton may not sync
  • GOG Galaxy includes a built-in store‑agnostic marketplace, Steam’s store is limited to Valve’s catalogue
  • Steam lacks a native tool to export GOG Galaxy’s metadata or collection files

Ouvrir vos fichiers GOG Galaxy

There is no documented method to directly open or export GOG Galaxy’s library files on Linux. Users typically recreate their collection manually in Steam by adding non‑Steam games as shortcuts. If you have exported CSV or JSON from GOG Galaxy, you could script the creation of Steam shortcuts, but that requires custom work.

Passer de GOG Galaxy à Steam, étape par étape

  1. Install Steam from your distribution’s repository or Flathub.
  2. Log in with your Steam account or create a new one.
  3. In Steam, go to ‘Games → Add a Non‑Steam Game…’ and browse to each Windows executable you want to launch via Proton.
  4. Enable Proton for each added title in the game’s properties.
  5. Import your GOG Galaxy save files into the appropriate game folders if they are not automatically detected.
  6. Rebuild your friends list and groups manually within Steam.
