I liked the Harvest Moon series back in the 90's but it's shocking how one guy was able to make the definitive game of the genre on his own. The farming/mining/fishing/upgrading gameplay that makes up most of Stardew Valley is addicting, sure, but what really sets this apart is the incredible attention to detail. The town you move to feels alive, with periodic holiday celebrations, dozens of characters with their own storylines and motivations, and all sorts of little side tasks to work into your daily tasklist and keep you busy for many in-game years. I put this down when I reached the "ending" but I'm ready to pick it back up soon to check out some of the later-game content.
