> Games 1 through 9 aren’t on the platform anymore I would just like to add that Steam assigns ten IDs to an app, making appID 10 the first game, 20 the second, and so on. Though Steam has delisted games, they are still available from one's user library, provided they have a valid license for it. If, for any reason, it's not visible in the library, one could use the DepotDownloader[0] to download any version, past or current, directly from Steam's servers. I've had some fun with it, visiting release versions of favorite games, seeing how much they've changed. Great script! This will definitely help some game archiving enthusiasts.

There's also DepotDownloader as a more generic tool that lets you download anything from steam, including past version. https://github.com/SteamRE/DepotDownloader. Being more generic, it probably can't archive your whole library in one go. I use this to download historical versions of a game to help with reverse engineering to archive dialogue trees from a game https://dialogue.destiny.report

> I love HL, and if I could get hold of it without Steam, I'd have it, but I don't know of a way to do that, and I've lost the copy I originally bought because leaving Steam meant loosing everything. (Used) physical copies are still reasonably available. For Half-Life 1 those should all be pre-Steam AFAIK. The high seas are also always an option - don't let others' morals stop you from preserving your childhood memories. Also while I don't mean to be uncritical of Steam and Valve, loosing access to your games sounds highly unusual. Did they actually take your stuff or are you simply choosing not to use Steam? If its the latter and you still have a working login, then you could download your Games using Steam, steamcmd [0] or reverse engineered downloaders [1] and play them forever using the Goldberg Emulator [2] instead of Steam.

Even chunks are checksummed. Or at least they are in third party implementations. [1] One thing that happens is some games keep config files in their game directory instead of using a host OS user directory and thus those games will fail validation after any configuration change. Combine that with mods that break games, but the mod files aren't in the manifest and thus invisible to validation, can create scenarios where users are doing repeated full validations and still having issues.
