Sorry for the necro, but having seen other posts receiving new replies after 4-5 years I figure the rules for such things are a bit flexible around here...
Anyway, I'd love to try and use these maps in the latest OXCE but I don't want to install them as a permanent fixture. Before I either dig deep into learning how the scripting works, and/or become completely disinterested in playing this game ever again, has anyone possibly already done the work required to make these maps work as a simple switchable mod?
EDIT: Heh, have answered my own question by accident. Was looking at other mods, and got directed to the .io mod portal where I found Vanilla Variants:
