Yes — Steam sells DRM-free games. Many indies (and a surprising number of AAA titles) ship without the Steam DRM wrapper, meaning you can copy the install folder, run the executable, and play without the Steam client ever opening. Here's a curated list to start your own offline library.
How to verify a Steam game is DRM-free
Install the game through Steam as normal.
Fully quit Steam (right-click the tray icon → Exit).
Open the install folder (right-click in Library → Manage → Browse local files).
Double-click the main .exe. If it launches and plays without Steam re-opening, it's DRM-free.
Each title below has been reported DRM-free on Steam at the time of writing. Publishers occasionally change wrappers — verify with the steps above before relying on a copy.

Why buy DRM-free on Steam at all?
Steam is convenient, but the Steam client itself is DRM — lose access to your account and you lose your library. A DRM-free game on Steam gives you the best of both worlds: Steam's discounts, cloud saves, and workshop, plus a folder you can back up forever and run offline.
Publishers can add or remove Steam's DRM wrapper at any patch. Treat this list as a starting point, not a contract — always confirm by quitting Steam and launching the executable directly.
