Very addictive game and lot's of fun online,
the community is very kind in all the servers I've been in.
It has a very quick start up, no nonsens intros.
And getting into a server/world is also fast, and those worlds are massive!
It has like a continue save, so if you are done playing you just hit the quit button....
...aaaaand it's gone. :P

A low end PC can run this easily. (I know, I had one.)
With all the settings low, it stil looks very nice.
Now that I've got a new PC I like the graphics even more and, when above ground,
I often stop doing what I do, simply to watch the sun set or rise. :)

Edit: Have you seen the big update pictures yet?!
This is gonna be even more beautiful!
I think this is the first game I own that will hit the 1000h play time mark. :)
