The personalities determine how likely a computer player is to attack you. Personalities are:
Choleric
Phlematic
Melancholic
Sanguine
The choices for basis of law are:
Theocracy
Oligarchy

Combat follows Civilization rules with a one for one unit loss. There are no technologies to obtain, but each player's progress is tracked through phases such as clan and tribe. The game is won on the basis of accumulating trade.
The different laws and personalities and random starting positions are the only game variations. There is just one map and no varying difficulty level.[1]
Reception
Jerry Pournelle in 1985 reported that Avalon Hill's Incunabula and By Fire and Sword "snaffled off more of my time than I could afford".[2]Computer Gaming World that year noted the resemblance to Avalon Hill's Civilization board game and wondered why the company did not call the video game Computer Civilization, and cautioned that because of the lack of map variations or difficulty levels, "the probable solitaire life of the game could be rather limited". It nonetheless concluded, "Incunabula is an interesting and enjoyable multi-player game. The combination of combat, good trading, and diplomacy will give a wide variety of gamers something worth a closer look".[1] In 1990 and 1993, the magazine gave it three stars out of five.[3][4]
