I used to belong to a site called “Ancient Sites” or something like that.
It featured 3d reconstructions of locations like ancient Rome, Macchu Pichu, Memphis, etc that you could wander around. I used it when I was reading Collen McCulloughs books on Rome so I could ‘be’ at the locations and ‘see” the buildings. Very cool.
You could also take a name for an avatar and interact with other members of the site. I think I was a Roman Senator named Antoninus or something, but I didn’t really get into that side of it too much.
Don’t know if it is still in operation.
Me too, always inflexible (after that first blush with cool graphics and such, it didn’t have a lot of options) it deteriorated into a stagnant, ancient historian wannabee version of MySpace; later it was revived as Ancient Vines or something like that, I tried that I think, anyway, it’s probably still around somewhere.
