Assassin's creed 1 part?

Ar
- in Xbox
1

Hi so yesterday I discovered a game called Assassins creed looks really cool would buy it for me too but As creed 1-2 is only for Xbox 360 and I have Xbox one and only the kicks part of the first three is playable for me Do I have to have played the first two to know what it's all about and so or does it matter and I can play all Assassins creed games together? Can you also tell me which part is which from 4 to the last

De

Actually you should play the 1, 2.0, 2.1, 2.2, 3 in the correct order (is a connected story)

Then comes

Black flag

Unity

syndicate

Origins

Odyssey

Valhalla

Historically, odyssey comes before origins
