I've written some (nothing very notable) and played others (mostly roguelikes as the price and "does it run on OpenBSD?" is right.
A board game where cards are used to move a ship around. Kind of like RoboRally on ice, except less fun. It mostly shows that movement cards dealt randomly from a deck can result in very bad hands.

A one-level roguelike exploring a wizard's garden for food and sudden death.

An autumn 2022 Lisp Game Jam game, but can be played without a computer. It is a two-person board game, maybe a chesslite.
Somewhat like Lode Runner, except for all the things not implemented, plus bombs plus you can rotate the level map.

A 2024 7DRL attempt.

Supposed to be a Roguelike, though probably more a top-down shoot-em-up but where the @ cannot do any shooting.

Online wins are the ones that really count.

A restoration project of rogue (~1981), the oldest version I could find on the Internet. Modern compilers really did not like the pre-ANSI code, and there are various random gameplay changes because why not. Probably this version is too easy.

Working on 40+ year old code that you did not write and other people have hacked on now and then is probably a good skill to have, at the very least.
On the history of roguelikes, the following is a pretty interesting posting.

A modified version of some version of trek(6) from the OpenBSD base system. Features a different RNG and a few quality of life improvements.
NetBSD 10 imported warp(6) which I probably should check out one of these years.
