Amstrad never made it over here, as far as I can remember. The C64 being as widespread and long-lasting in the marketplace as it was really attracted alot of attention, and due to most being familiar with it in one way or the other (owned one, played one at a friend's,) really puts it up there for people looking to go back in time a bit. Sure, the same games were released for alot of the old machines, but a particular rendition of a game would bring back memories for someone who'd played it 20 years ago, whereas another system's version of the same game would just look like crap because it was different.
