Undertale

In this billion-dollar industry, games tend to take themselves very seriously. There's not much room for thinking outside of the box, or comedy. Indie games often fill that gap, and few more than Undertale. Crafted by a single man, Toby Fox, the game is full of humor, parodies, and great characters. It doesn't try to be something it's not, choosing a very simple art style that fits its humble roots. Instead, it focuses on detail within those boundaries. There are hundreds of clues to discover, little bits of lore, tiny items that make the underground world feel real. Though the RPG has puzzles and turn-based combat, they're partly just a medium for story and comedy. Just when you think you have a handle on things, Holt pulls the rug out from under you with hard-hitting emotion and a subversion of gameplay tropes. You never know what to expect with Undertale, and that's what makes it so refreshing. The multiple gameplay branches make multiple playthroughs viable, with references even to actions from your last playthrough. The sheer variation in enemy encounters and its ability to encourage empathy makes it one of the most innovative games of this decade.
