There's a lot of cool structure mods that update and add some vanilla-feeling structures to the world. Along with adding many new biomes with the Biomes O' Plenty mod. No modpack specific progression system so go about your world at your pace.
No story or strict goal, just a lot of mods.
There is a high chance I add more to this so keep an eye open for updates etc.
