We have the movie thread, so let's talk about games as well.
I was more interested in indie games than the big AAA stuff, so my top list might look a little bit strange:
My top 3:
Pokémon Go might not offer the deepest gameplay, but it was an amazing experience. People played it a lot in the park in front of our house and so it felt like a social experiment to me. Old people, young people, casual and experienced gamers helped each other catch some rare Pokémon. I liked this a lot and still hatch my eggs when I go for a walk with the dog. It's the first mobile game I really got addicted to.
Stardew Valley is a cute and time consuming game in the style of Harvest Moon. I am sure most of you heard about it because it was very popular on Steam. I never liked Harvest Moon but I played a ton of Stardew Valley. So much fun, because you don't just manage a farm, there are many RPG elements as well.
Curious Expedition might be especially worth a look for Eggyslav, because it's about history . But I think everybody can enjoy this little gem. It's from a German indie developer and combines roguelike challenge (it's really hard in the beginning) with addicting stragtegy. You plan an expedition, collect treasures and try to survive.
Tabletop Simulator is a honorable mention, because it was not released in 2016. But I got it this year and use it a lot to play board games with friends who don't live next door. The Doom boardgame, Agricola, Illuminati,... It's an incredibly powerfull tool! We even started Dungeons & Dragons.
Which games did you enjoy most in 2016?
