I Takes Two wins for me.
I have mad respect for Hazelight Studios dedication to bring us great couch co-op experiences.

Definitely Steamworld Dig 2, The gameplay loop of digging for resources and upgrading to dig further and further is SO addicting.
The platforming sections are really great too.

By far Minecraft, I think it is or at least was a genius game. I think MS has ruined the game adding too much stuff, added another massive underground area and ruined the diamond grind and way too many bioms and uneven terrain, generated maps is always a disappointment but from the short few months before 1.0 and a few years after that game was something else, esspecially PC in 2011. The terrain was perfect, the grind was perfect, the mods were always unique and completely transformative. No matter how you played that game it was simply genius, eheter you were in survival or on a server using World Edit and building mega structures or projects coordinating a few hundred people it was magic.

The kids then got on and crowded servers, late 2011 and 2012 and kinda ruined it but when we autistic 20 somethings got together we created some incredible stuff, I was on a server where they filtered kids out with building tests and it was so much fun. I have only got on for a few survival sessions on my lonesome on console that would last a few dozen hours each every few years since but everything I am more disappointed with how they've handled the procedural generation. Such a pity that such a perfectly tuned game was wrecked from over adding content and features. I'm sure mods could fix this but I don't plan on a PC or a Laptop anytime soon that would be able to handle nodding that game reasonably.

I voted for Mirror’s Edge, which is not only my favorite swedish game, but one of my favorite games period. The platforming and overall flow of the game feels incredible, the visual design is so cool and complement the gameplay perfectly.

One of the few perfect games.

Mirror's Edge

One of my favourite games. It's coming up on 20 years old and still looks beautiful, thanks to the minimalist art style and such great use of colour. Solar Fields' soundtrack is excellent too (and his one for Catalyst is even better).

The first person platforming system is the icing on top; has an incredibly high skill ceiling, so when you nail sequences without making a mistake you get a great sense of momentum and feeling of accomplishment.

Other: I had a silly amount of fun with Just Cause 2 and the multiplayer mod was great too.
