Can't say I've ever had them stop working, but I've had lots of problems graphics wise. A few seem to just jutter their way along, merrily ignoring the rest of the world.
One thing that surprises me is how some games that are ten or so years old, actually have the options for big resolutions - for example, Populous: The Beginning and Ghost Recon seem to be able to go up to the 1600s.
I'd imagine that a lot of games would have trouble running on Vista, though.
By the way, I found a couple downloads for packaged Fallout 1 and Fallout 2 combined, not legal but if you know where to look they're super easy to find(and have lots of seeders too(hint))
That's probably the one I, ahem, didn't download on Friday in a couple of hours. It isn't 1.09gb, by any chance, is it? Because that's definitely not the one I, ahem, acquired.
Well there's "Fallout; The Ultimate Collection" which is 3.49 Gigs, but I also see the one you're talking about which is simply just Fallout 1 and Fallout 2 that is 1.09 Gigs. Not sure what exactly the Ultimate Collection is, probably Fallout: Tactics or whatever else they have.
Haven't played Tactics. I heard conflicting reports about it. Then there was the abominable console game "Brotherhood of Steel," which, from what I understand, was simply a bastardization of some of the topics/themes of the Fallout universe in an isometric overhead shooter format (also didn't play that). I definitely give my seal of approval to the first two games, with the caveat - save often and in different save slots. There are some glitches that can be quite irritating, so it's nice to have multiple points from which to reload the game.
From what I've read and heard, any games other than Fallout 1 and 2 aren't worth playing.
Don't know if Voll or VD can back me up on that.
Fallout: Tactics was an abomination, and I've never touched Brotherhood of Steel.
These were basically seen as milking the franchise by serious Fallout fans, which is one reason why Fallout 3 is such a big deal. They've got a lot of expectations to meet, but I don't think it would be difficult.
