La boite contient un livret de règles, un livret d'aventure avec 3 scénarii, et des aides de jeu.
Du dos de la boite:
" In Time & Time Again, you can stand beside Napoleon at Borodino,
watch the pyramids being raised, journey down the Mississippi with Sam
Clemens, travel with Marco Polo to Far Cathay, join the legions and
cross the Rubicon.
The Time & Time Again game system features
complete rules for character generation and skills with the most
realistic combat system, armed and unarmed, ever published. Chapters
cover climate, geography, languages, economics, travel, manners and
morals, society and culture, technology and more. The physics of
Temporal Translation (time travel or T2), are presented in sufficient
detail to allow for easy use while preventing a paradox. There are maps
and charts, character sheets and three complete scenarios. Just add
dice, players and imagination! Welcome to the BTA."
