Path of the Goddess came out last month and its legitimately a game out of a time lost. When rentals made you less stingy about every game needing to be 100+ hours of masterpiece to be worth it, and AAA companies releasing AA experimental games to do weird shit with. And then it still ended up being way longer than expected anyway.

Rusty's Retirement was a dumb little game that had an idea and committed to it harder than you'd ever expect. Which is being in a tiny window across the bottom of your screen to be an idle game you do between work sessions to help relax. It even adds a mode that makes things grow slower if you are playing too much.

Against the Storm came out of EA to show that every game in the roguelike genre doesn't need to be a fucking deckbuilder and can even be a wildly unexpected genre like a city builder and it work out flawlessly.

And for consoles, Unicorn Overlord was there being both maximum horny and fucking art in terms of its presentation/graphics. While still being a solid enough strategy/RTS game.
