If a friend hadn't mentioned that this game might be worth checking out, I still wouldn't have even heard of it. I don't care for the block games like Minecraft or even the more complex Landmark, but this has that certain special something just right that makes it quite fun. My whole family has been playing since we first heard of it.
The game is called Trove, and its free to download and play.
These screenshots are from my club world, Chunksville, where we basically have a bunch of land to do whatever we want with, but the game has lots of questing, leveling up, and customization to enjoy too.
Any of you who play Trove or get it soon, just friend me and send me a message. My name in game is Weeger.
Metroplex, the Borg cube, and the Starfleet base that my friend built all have full interiors to explore, play hide and seek, or whatever flips yer lid. Let me know if ya want to visit Chunksville, or join.
