Today and yesterday I played about six hours of Terraria each session with friends. I don't know how the time flied by, but I was completely unable to keep track of time as I was slowly and steadily hacking to bits pieces of demonstone and other rock-like substances.
Before I knew it, I already started trespassing into the territories of 4-AM and on. Those are the times where I draw the line, mainly because my conscience feels so bad it drags me to bed at an alarming rate.
The reason why I continued to do so today, was that Terraria had a huge content update. To which my friends asked me to join. I at first thought I would be able to discontinue playing after a short while. Alas, this was all preemptive thought. When I was in the midst of spelunking, there was no stopping until now, which was 3-AM
