Well here's my explanation (I sometimes get similar feelings). IDK about you, but I've been playing this game for a little under 7 years now, which is actually a pretty fukin long time to play a game for. I realised recently that for probably about the first 4 years I played it, I actually took intermittent breaks, and went off and played other stuff in my free time. Furthermore, when I did play Minecraft, I was always doing different things... SMP, SSP, Tekkit/Modded Stuff, PvP (on MC-War, and EW), Building... etc. Never staying still. And then I also realised that in the past 2-3 years I've basically just done EW and EQ. That, added to the fact I am busy as fuck with school, means that Minecraft is not the addiction it used to be. Not saying I don't enjoy it though, or that I'm gonna leave EW behind
