Subterranean Switcheroo is an MCreator mod, notable for holding the title of most downloaded MCreator mod from May 2019 to Present.
Subterranean Switcheroo is built around finding ways to get more vanilla resources to the player in large modpacks where vanilla resources are needed by different mods in amounts that may be reasonable when those mods are used alone, but become untenable in groups.
It does this through the addition of ores containing multiple different resources, which can be extracted depending on your need, a boss fight, where resources are doled out as rewards, and plants which allow surface-dwellers to get lapis of their own.
It contains every feature of Placebo Effect and Obsidian Ore, and most features of Nicer Nether.
