The Lord of the Rings: Return to Moria is an interesting and unique take on the survival/crafting genre.

As the name suggests, you play as a group of Dwarves who return to Moria and reclaim it for their own.

Playable solo or with friends, you'll venture into the procedurally generated depths in order to mine its treasure and rebuild your home.

Needless to say, you'll also come face-to-face with some Middle-earth monsters along the way. This includes Goblins, Orcs and Cave Trolls.
