If you're after a bit of truly adult fun on Linux, I urge you to try out 'Oh...Sir!! The Insult Simulator'. It's utterly insane, brilliant and so damn funny. This post is probably not safe for work.
If you are after an amusing time-killer, or perhaps something to entertain the kids, you may want to check out 'Clouds & Sheep 2'.

Megapolis is an older title, but positively rated and it's now on Steam with Linux support. It's a small city building simulator, something more casual than say Cities Skylines.
