You could probably play them on a lot of PCs tho (if you have a PC) - not quite the system demands of modern day games. Good Old Games has them for cheap, patched and able to play on XP (and possibly even Vista.)
Yep, it runs fine on Vista once you remind to turn on the Windows 9x compatibility mode for the game executable. And it runs perfectly normally and certainly not too fast or something like this, it runs just fine. You'll have to look further in the past to find games whose speed was depending on the machine's speed. I think that even Dungeon Keeper would run smooth on a current machine.
Sorry but they most likely won't be released on any console.
Simply not worth it as most console owners probably wouldn't have even heard of them.
Well, since almost everybody in the world of gaming has heard of Fallout
3, I think most of them can't help but wonder how the previous Fallout were, even if they didn't heard about 10 years ago. So like the old classics such as Mario or Sonic, I think it would be a prime target for oldies sold on PSN or Xbox LIVE. Well, except that a 640*480 in 256 colours game might not render that well on a brand new HD TV, especially one like Fallout, which, even ten years ago, was quite outdated technically.
