Game of the Decade
D1. The Legend of Zelda: Breath of the Wild - Just simply the greatest game ever. Beautiful, inventive, magical and just down right amazing.
D2. Pokemon Go - This is more than a game. It's literally changed my life. It got me out of the house and interacting with people. It's helped me get fitter, introduced me to new friends, got me laid and just generally helped my mental health.
D3. Super Mario Odyssey - The BoTW of Mario games.
D4. GTA V - the single player story is nothing special but everything else; the setting, map, online, is just great.
D5. Halo Reach - The last great Halo game. Loved the Campaign and the online multiplayer was as good as it was in Halo 3.
D6. Portal 2
D7. Super Meat Boy
D8. The Last of Us
D9. Rocket League
D10. Super Smash Bros. Ultimate
Just missing out: Celeste, Mario Kart 8 Deluxe, Black Flag, New Leaf, 3D Land...
