There isn't a single adventure game I'd place higher than this exquisitely crafted masterpiece. The writing is top-notch, the puzzles are fun and relate to story and atmosphere, and some of the visuals are still stunning to this day. The follow up, Dreamfall, was nowhere near as good, and it was an excellent game. Simply put - it's the most fun and artistic pleasure you can wring out of the adventure genre. And it lasts a very long time without a boring moment.
