Bring Your Own Dice is a quick-playing points race for two or more players where you build your own die pool, but only your highest-scoring die scores each round. Your non-scoring dice may trigger additional effects if you're lucky and if you bought them.
An exploration and building long-form game for one civ-building enthusiast, played on an origami fortune teller (aka: a cootie catcher). (With expansions and variant rules to play co-op, co-petitively, or competitively with any number of players (though 5 players total is a good upper limit))
