The closest I ever got to gaming was Abe’s Oddysee (I guess Robot Unicorn Attack doesn’t count.) — but I do enjoy the odd game now and then.
Here’s an absolutely subjective selection for killing (not too much) time.
Lunar lander *
What: a simple but challenging game where you have to land a rover on the moon.
How to play: online on moonlander.seb.ly
Why: because it’s so pretty and monochrome.
What: sheep invaders. It’s a vim plugin demonstrating new vim features (as in, popups in 8.2).
How to play: by upgrading vim and installing the vim plugin.
Why: because you can shoot at neon sheep flying across your vim screen and pooping at you.
What: space invaders in your console.
How to play:
brew install ninvaders or
sudo apt-get install ninvaders.
Why: you shouldn’t have to exit the console to play space invaders.
Google console text adventure game *
What: a text adventure game. I didn’t find it too interesting, but it’s an honorable mention.
How to play: Google ‘Text adventure’ (really Google, don’t DuckDuckGo) and open the console. Why: there’s lots of creative stuff people do in the console. This is one of them.
Bonus: Chess *
What: Good old chess, human versus machine.
How to play: If you have a mac, you have chess.
Why: Being beaten by the computer feels a bit like being part of history.
