The Talos Principle. It's a first person puzzle game much like the Portal series. It was made by Croteam who is famous for Serious Sam. For a company that specializes in shooters, they handled the puzzle genre really well. The puzzles are only half of the game's plot while the other half focuses on AI personality, humanity, life & death, religion, temptation, etc. And there are lots of easter eggs. It's a game worth experiencing.
