If I can't play the modern day time, it's another positive for me as I hate the present day crap.
Personally, if Ubisoft was to ever take a year off, they should just "reset" the franchise with no present day, no abstergo, no animus, etc. Instead, you should simply play as an Assassin in a set time period and place and the story should be built in the game itself. Each following game would be in another time period and place but always moving forward. Eventually, the final game would be set in the present day and that's where it would conclude.
I only started this franchise with Black Flag and it was because of the setting, atmosphere, immersion and setup. I didn't like the present day at all especially since it's in a 100% first person view which I hate. For me, it's Rogue > Black Flag > Unity.
I played AC II after Black Flag which was probably a mistake but while Ezio is a good character, the game was slow and boring for me. I quit in sequence five or six. Can't remember which.
With that all said, im obviously not burnt out or to where AC needs to be "reset". My major complaint from Unity was the controls, free running and response time. It was worse and more aggravating and frustrating than either Rogue or Black Flag. The free running should simply be "hold R2/RT" and move the analog in the direction you want to go. The "X/A" button to jump shouldn't exist. To go inside windows, etc., holding R2/RT and moving the analog in the direction of the open window should automatically make the character go inside the window. Other than that, not being able to whistle(or knock) to get an enemy's attention and not being able to use an enemy as a human shield were my other complaints. After that, way too many NPC's on screen and the "last known position" crap.
Majority of my complaints weren't complaints in Rogue or Black Flag. I'm just hoping that Syndicate fixed majority of them and every gameplay element (like that circle ring around the character) should have an on/off option. This way, the user can play the way they want.
Majority here aren't hyped for Syndicate but I am as it's my last pre-order and pick up on release day game until February as I don't have Xbox One (Tomb Raider) and I have no interest in Fallout 4. Six more days to go!!!
