Steam Classic

If Redstone 9X is the 1990s gaming den, Steam Classic (ruled 2026-07-02) is the room next door, five years later: the era when Steam was olive-green, angular, and slightly hostile, and the games it carried were the best PC gaming would ever be per megabyte. A sanctuary wearing that grammar whole — a green-on-green Windows 98 SE face over Xfce, tuned until the chrome reads like the client did in the orange-box years.

The catalogue is the point: Valve’s golden run and the source-port canon around it — Quake through its modern engines, Doom through GZDoom, the id and Valve lineages treated as living software with a proper launcher shelf rather than icons scattered across a desktop. Same law as the rest of the Castle: every launcher declared in DotCortex, the habitat rebuildable from source, nothing hand-installed and forgotten.

It began, like several rooms here, as a lab — an experiment in getting classic Steamworks-era software running clean under a container — and earned promotion to a sanctuary when it became obvious it was a place. Screenshots when the valve turns.
