How can I understand assassins creed games better
its hard to understand
You can read the books, as I did. It helped me understand thestory so much better. or, you can wait until the movies come out. The first one comes out next year
Compare most of the games to actual historical moments
Play the games.
Really try to understand the talking in the game. I played brotherhood first and that got me really interested and then I played the rest later
if you means Information of details of game Go here http://en.wikipedia.org/wiki/Assassin's_Creed but if you want know things about passing missions or something like that, only way is experience it by yourself Good Luck :)
