From Ultima Codex
Ultima Collection and contains on 12 pages the maps of all the nine games in the compilation. However, the maps included are of a lower quality than the original maps contained with the different games. The maps are small and in grainy black-and-white, missing many details as well.
It is unknown why Origin created a low quality atlas, when the original color maps had been at their disposal for its production. One possible explanation could be budget restrictions by Electronic Arts.
