Back in the day, playing /usr/games/hunt against other people would hone your VI movement keys muscle memory rather quickly. On the multiuser Unix systems at Purdue, it was typical to have at least half a dozen people on the server, with explosions going off like fireworks. We ran the mod where you could collect 200 ammunition for the nuke, which would destroy a third of the screen. https://man.openbsd.org/OpenBSD-current/man6/hunt.6 https://man.openbsd.org/OpenBSD-current/man6/hunt.6 We also had Larry Wall's (yes, that one) video game Warp, which was a lot more action-oriented than the original Star Trek video game. It also used the same hjkl movement keys. http://ftpmirror.your.org/pub/misc/unixarchive/PDP-11/Trees/2.11BSD/usr/src/games/warp/README http://ftpmirror.your.org/pub/misc/unixarchive/PDP-11/Trees/... And of course there was Rogue and Nethack, but those are a lot better remembered these days.
