Bethesda just re-released Fallout trilogy on Steam. The single games are available for $9.99/€9.99 while the entire trilogy costs $19.99/€19.99 in total. I don't have the Fallout trilogy on Steam, but Infinitron on the RPG Codex offered a list of the changes made by Bethesda. Contrary to some people's fears, Bethesda barely touched the games at all, and their changes can be summed up to some updated legal text (it now mentions Bethesda Softworks) and the integration of the high-resolution mods for Fallout 1 and 2 (though it's possible to play the games completely vanilla in "classic mode"). Also of note: the games now make use of Steam's cloud save functionality. It remains to be seen whether the games will be re-released on GOG or any other other platform that doesn't sell Steam keys.
