I've never played Minecraft (if you don't count my futile attempts at playing Minicraft on my Windows Phone), but now it seems a (free) version of it is coming to the Raspberry Pi. Not only can you play it like the ordinary Minecraft, you can also program it in real time! Check out the video below.
So, if I haven't gotten started with Minecraft yet, this is a golden opportunity for some procrastination! It's hopefully going to be released by the end of this year, and I can barely wait!
