I play single player almost exclusively. The stories I hear from multiplayer make my sphincter tighten. This is mostly due to incomplete faction systems. Make sure you understand the concepts of '
Early Access', '
sandbox', and '
alpha'.
There are two main branches of multiplayer. Creative group builds and hardcore PVP. They don't always segregate, so if you don't want your stuff blown up, play single player.
Way to many people around here that get upset when the next patch breaks things. Whatever you make today, will be worthless in 3 months. (not quite true, but you'll save yourself some frustration if you think like that)
We have just had a major patch. Patches are on a 2 week schedule. I suggest you
read this thread to see what you are getting yourself into.
(ps: I've been called an 'elitist asshole'. I prefer to think of myself as 'against stupidity'.)
