You can add onto this list if you would like.
1.) A modern day storyline (not a seperate game, but for when you leave the animus) with a new badass modern day assassin with awesome hidden blade modifications and guns. The game would be awesome with assault rifles and the like, to kill templar agents.
2.) To remove the one game a year deadline and put quality over quantity.
3.) This as Assassin's Creed 6
4.) Armor to be brought back
5.) Viewpoints to be puzzles to get up
6.) Tombs (nuff said)
