The game appears in the library as a demo version (there will be a "Demo" label bar), but it is actually the full version and fully playable. The word "Demo" will not appear in the game’s title — in the library, the game is listed as Killzone Trilogy Killzone Trilogy (PS 3 version, launched via RPCS3) On my side I guarantee that the game will not change the game files (original game files), images, title and will forever remain in your library. Basically, you will get Killzone Trilogy in your collection, the only difference will be the app id and that you won’t be able to use the Steam community center (upload screenshots, write guides, etc.), and it won’t show up on your profile, can’t be added to a showcase, but it will appear in your library, and you’ll be able to download and play.
