The Ship is a game that's hard to explain. It vibes with the likes of Among Us or Trouble in Terrorist Town, while having "needs" feature like The Sims and the feeling of a 2000's Source engine FPS.

The Ship is an online game where you are thrown in a somber game of murder on a cruise ship. Each round, you are the target of another player while also being given a target to kill with one of the hundreds of weapons available from kitchen knives to billiard sticks, while not forgetting poison syringes or emergency flare guns.
The concept is simple, right ? Okay, now add the need to eat, drink, take a shower, sleep (while being targetted by other players !), talk with people... There are also surveillance cameras and policemen all aboard the ship that will send you straight to a prison cell if you are seen carrying a weapon.

This game was way ahead of its time and I think would have been a huge success with a decent communication about it.

A somewhat obscure Source Engine game that I occasionally play sometimes (mostly with bots). It's basically like TTT or Among Us in some ways but in a steampunk theme. Not worth buying because there aren't any servers for it (unless you check the servers tab and use "The Ship" dialogue in the Steam menu.) But, even if you buy it you're entitled to get a free gift copy of the game that you can give to anyone else, though I doubt anyone else would be interested in playing this game more than once or twice times.
