Gamescom 2015 - One of the most unique games I've ever seen would have to be the sleeper game 'Unravel'. Surprisingly, Electronic Arts is behind the game, where you play as a single thread of yarn that slowly unravels as you move.
The game is helped by its beautiful backgrounds, inspired by North Scandinavia. Unravel is a physics-based puzzle game platformer, where you have to travel across the environment solving puzzles that are in your way. It's a super-cute platformer that reminds me of Little Big Planet in a way. Let us know what you think in the comments below.
