Traditionally, if someone asks whether you can survive "the end of the world"—meaning the metaphysical destruction of all things and a return to some kind of void-state—the answer is a resounding "no."
"Ragnarok left a broken and unbalanced world in its wake. Now caught in an endless loop of destruction, you must nurture the World Tree Yggdrasil back to life to break the cycle and restore the Nine Realms to their former glory," says the official description.
Most interesting here is that each attempt at city-building is hounded by the encroachment of Ginnungagap, the primal void from which the world sprang and to betdog which it was fated to return. Your settlements are forced to embrace a nomadic lifestyle, as each new island you explore to inevitably collapses.
It looks to have a blend of gameplay inspired by placement-driven city builders like Islanders, but at the same time taking inspiration from the excellent gameplay of Against the Storm, which is very good sbfplay indeed.
Meanwhile, expeditions return to The Holt, a permanent settlement protected by the magic of the world tree that houses your clan and lets you trade, store, and stockpile upgrades for future expeditions. It's also where you'll interact with the scions, heroes, gods, and monsters from Norse myth that can lend their powers to your settlements.
You can find Roots of Yggdrasil on Steam.
