I highly recommend Space Station 14.
It's an amazing roleplaying disaster simulator, where around 100 players are trying to keep a Space Station afloat. From doctors, through police, scientist, engineers, to cargo and barmans. Every role has a way how to blow up the station - Engineers generate energy through a contained singularity or a Tesla ball. If that escapes because you forgot to repair the cage, the station is fucked.
Scientists experiment with artifacts that give you research for doing stuff with it, and it's generate what does doing stuff with it do, i.e if you wrench it, it does something. Something can be "spawn a monkey", "print money" to "thermonuclear explosion".
And add to that tower of cards some people getting the roles of antagonists, which can be anything between "Syndycate agent that has to kill the captaion", "a blood cult needing to steahltily sacrifice people to ascend", "pantient zero that turns into a zombie", or a "syndicate deathsquad that has to fight to the station nuke and trigger selfdestruction".
It's massive fun, and I highly recommend it.
Oh, and that's basic SS14. There's also a very popular mod - Roundy Marine Crops, which si basically ~ 100vs100 Alien vs Predator, where you play every role imaginable from Marines that are deploying planetside to fight Aliens who are digging in.
If you need convincing, this is the best short story video that absolutly sold me the game. It's aboslute cinema, the way it's told. https://www.youtube.com/watch?v=jfjz1MnlxzE
Then there's also the almost legendary video about Space Station 13 from Sseth (this is basically a reimplementation into C#) that can also give you the vibe of the game. But I'd recommend the previous video more.
Note: There's currently some drama with main maintainer, who had control of the launcher and server hub, starting to act extremely egoistically and hostile, holding the whole game and it's auth database hostage, hacking discord servers, banning random people, and in general being a dick. That is why I have linked the playss14 launcher, which is a fork from the rest of the community to sidestep the demands and general dickery the maintainer is doing. It's pretty ugly. The game is on Steam, just like it has other page, but that would lead you to the launcher that's currently being ransomed. You're better off just getting the alt launcher from playss14.com linked above.
