First, I tried the old demo version of MCPE. Aside from spawning in an ocean and drowning the first time, I had no clue what was going on, what I was supposed to do (can those things outside groaning break through doors? do I need more than three doors between me and the outdoors? are they still there?) and gave up within 15 minutes.
Then, quite a while later, I got the XBox 360 version right when it first came out in a box (as opposed to XLA). I hurried home, put in the disc, and disappeared into Minecraft. I think I surfaced for dinner (and it was my night to cook, too!). Not long after, I discovered this forum.
A month or so after that, I got Minecraft for the PC. I've been addicted to that ever since. I also have the newest MCPE, and of course I still play on the XBox sometimes, too.
