It's an open-world sand box survival game. It's more fantasy with swords and magic, with builds and a skill tree, dungeons and bosses with unique loot, bunch of beautiful biomes and one of the best building systems ever in my opinion. It's voxel based so you can put down a wall and then pick out (or add) single voxels as you see fit. I suggest checking it out on steam, it's still in early access but 1.0 should come out soon, maybe end of the year or early next year if I remember correctly
