Billiards just fits into the historical medieval period, with the first attested billiard table belonging to King Louis XI of France, in the late 15th century. And since standard swords-and sorcery fantasy settings are normally described as "pseudo-medieval", this is entirely "historically accurate" for the Fantasy theme.

The game of table billiards evolved from a game called trucco, now also known as lawn billiards - a game similar to croquet. It seems you can take almost any outdoor sport and bring it inside and play it on a table:

• Tennis → table tennis
• Football → foosball
• Ice hockey → air hockey
• Motor racing → slot car racing
• Skydiving → table diving
