Create a home base using Create, Functional Storage, and Refined storage. Make machines and storage systems, find pets and decorate your base. Then build a small village using the blueprint for MCA Reborn. Become a spouse, have kids, maybe Mayor? Then build a massive city using the Minecolonies mod!
Travel the world looking for bosses, dungeons, and other cities. Build Trains between them to revisit as you want! Try to figure out how to find enough specialized eyes of Enders to make your way to the end. This is gonna take a while... maybe my kids won't beat it in a week?
