Fallout 1/2/Tactics Leave Steam

As you can see for yourself by checking their Steam pages, Fallout 1, 2 and the spin-off Fallout Tactics: Brotherhood of Steel are not being sold on Steam anymore, though apparently Bethesda is working on getting them back to the service:

We’re working to return classic @Fallout games (1, 2, Tactics) to Steam and will provide an update when they’re ready to go.

…

We have to remove existing publisher info, legal text, etc.

As for whether the games will be back on GOG any time soon, it looks like it’s a possibility rather than a certainty:

we’ll have a look at other options once we handle Steam.
