Fallout 1, Fallout 2 and Fallout Tactics are back on Steam for $9.99 or in the Fallout Classics pack for $19.99. If you still don't have these and as they are no longer available from GOG, this is the only way to get them now. Although waiting on a potential future sale is an option to be considered.
Some details to note:
All three games have Steam Cloud enabled for save games.
Fallout 1 & Fallout 2 can be launched in either default or classic versions. Default allows for high resolutions and Classic is the original, unmodified release.
Fallout Tactics is unmodified. Multiplayer works with direct connect.
While Fallout 1 and Fallout 2 can run on Windows 8, Fallout Tactics is not Windows 8 compatible.
