Dragon Quest Builders is pretty radical so far.
Outside of that I started a game that I forgot I had bought from a steam sale earlier this year called Party Hard and it's pretty fun honestly. Basically think Hotline Miami where you need to kill EVERY MOTHERFUCKER mixed with Hitman in which you can't get caught. It's tough as nails but kinda silly in a fun way... like a bear will show up now and then to be the DJ and you have to kill him as well.
I remember seeing a stream of Party Hard and the twitch integration made it even more interesting. Basically the chat can vote on the next event and usually the chat voted for the biggest jerk move at first, only to try and play nice after the player had enugh failed runs that they wanted to go on. It's a pretty decent game even without (though the voice acting ain't it's strongest part).
And to not make my sole contribution a reply to a months old post, I have been binging on Final Fantasy XIV lately with some friends and man, for an MMO that games pretty good. The story has its ups and downs but it gets better as the game progresses (and even has the occasional cutscene that just screams Final Fantasy in the best way. Hell yeah multi-story jumping, blocking sword hits so strong they send things flying, etc). For a while I basically played it for the story even. The setting is fairly fleshed out and it's fun how after slaying a few giant, aether fueled monsters people actually start treating you like a hero. The gameplay is pretty fun too, not having to create new characters to try out classes means I can do some experiment and stuff like the "duty roulette" where you can essentially sign up to join a random person looking for a group for a dungeon in exchange for some pretty good experience points means that you will quickly get into even the optional dungeons or the early ones. And the game's pretty funny too at times, the amount of puns or references in questnames and such made me groan in appreciation a couple of times.
On the non-MMO front, been also getting into Kerbal Space Program again. Maybe this time I will actually send something to each and every planet and moon and not just make a bunch of stations and such in preparation for it :V
