My old friend introduced it to me, and at first I was just terrified of everything :o the monsters, falling, drowning, burning in lava >o< So I made a tiny house asap and felt shy to venture out. When I finally started exploring, I recall being estatic that I found stone xD --Only to realize later that it was the most common material in the map.
So yeah, that's how it started. Of course later on I got more into it and started building mansions on the beach and castles, which was fun :)
