Anyone that has logged into Fallout 76 in 2018 will get the original Fallout, Fallout 2 and the combat-focused Fallout Tactics: Brotherhood of Steel for free next month, Bethesda has announced.
Players will get the games as part of the Fallout Classic Collection, and should be able to claim them in early January. The collection was initially available as a pre-order bonus for Fallout 76.

Bethesda didn't specify where you'll be able to play the games but I presume it'll be through the developer's own launcher, rather than via Steam.
The games have been available for free before, and they only cost pocket change each but, hey, we're not going to say no. If you're a fan of RPGs then they're still worth playing, even 15-20 years after they were first released. You can read a couple of retrospectves on them here and here.
