Conan Exile, a sandbox, survival, base building game. Released in Jan 2017, in pre-release status on Steam. It's still being developed but currently has decent building abilities and although the desert is not my favorite biome, the Unreal Graphics Engine makes it beautiful.
As far as I know, this is the first game with full frontal nudity built in without useing a mod. There is a nudity filter so it can be turned off, partial or full nudity. Unlike Bethesda Software games, these human models are attractive.
Right now, there is base building, hunting, huge sand storms, crafting and thrall capturing, turning natives into your slaves to do chores for you including base defense. Future plans call for more lore, quests, biomes/map enlargement, (aiming to be larger than the Skyrim map), expanding crafts, expanding thrall abilities, a city system, farming, mounts, sorcery, expanded religions, and raids by NPC parties. The craft system is reasonable. Yes, there is lots of grinding for mats.
However, creative play/building is available via an easily assessable Admin interface.
There are both PVP and PVE servers. If you are familiar, server setup is similiar to Ark:Survival Evolved, small servers able to handle 25-50 players, I'm participating in an online PVE server, and have a large solo game build titled
Port of Tanis. Here is an example, a mountaintop religious complex, featuring temples for the 3 Gods currently in-game. I believe more will be introduced.
