Dates are based on discs' PVD creation date. Doesn't include every single Source Engine game disc out there, just what I either already had on my hands or was able to buy secondhand for cheap. All discs are of Russian region, so while most games on those are fully playable in English, a couple of them are not as English loc files were deleted to save on size (tried to note where applicable, might've missed something). Not feasible for me to upload everything to archive.org (takes actual 10+ hours per disc, more if upload fails and it's really prone to), so opted for what I personally felt are more interesting/rare builds.
