VintageStory - its an extremely mod-friendly survival based block builder.
I'm going to recommend VintageStory a lot - Blocks, built in mod support, survival based gameplay
~looking for modders who want to try something different~ - My VS model site vs.usagi.com.au
If you don't mind something more difficult, 7 Days to Die is a great game.
Watch out for the crabocalypse. Some say the day will never come. But it will.
Feel free to drop by for a chat whenever.
If you'd like to talk with me about other games, here are a few I play.
Team Fortress 2
Borderlands series (Borderlands 2 is my favorite game, ever. TPS combat is a lot of fun and makes up for the lower-quality story, in my opinion)
Elder Scrolls series
Warframe (IGN is something like That_One_Flesh_Atronach)
Pokémon series (HGSS forever)
Left 4 Dead 2 (Boomer files always corrupt though)
SUPERHOT (SUPERHOT is the most innovative shooter I've played in years!)
Dead Rising series (Dead Rising 2 is one of my favorite games, and the 3rd was a lot of fun. 1st has poor survivor AI and the 4th is bad)
7 Days to Die
Just Cause series
Come to think of it, I mainly play fighting-based games.
