Hands down the best game of this year. It's so rare for me to stay up late playing a game these days and I was totally hooked on this. Although it sounds like a simple (if daunting) concept, it's actually very well designed; there are all kinds of small details that make it great. Your job is to tidy up 3072 magic books, sorting them by title onto shelves sorted by category. The book titles are great, the mechanics are polished, and it's totally absorbing.
