I’ve had to set up a rota to use the Raspberry Pi. 1 hour each.
Someone… (ok – mea culpa) found that a simple

sudo apt-get install angband

will install a great rogue-like dungeon crawler.

I used to play this on my Archimedes 20-odd years ago and it’s still just as addictive.
No – it’s not 3d. No – it’s not fast. But holy-moley, it’s addictive.

We could stop at any point. Of course.
