Assassin's Creed Deterring?

I would say it is, if you look at the first 2 if i remember correctly were based around an Assassin named Ezio basically fighting the Templar and also assisting Leonardo in creating new weapons ect ect then i think it was when Black flag came out, the whole story revolved around a pirate that killed an Assassin to be one, while he was on a conquest to fight the more modern knights Templar while also aiming to captain his own ship.
I kinda forgot the story of the most recent game so yeah this is as far as i can go

Deterring? You mean deviating? The original was about penance and eventual betrayal with a side of kidnapping.
With Black Flag and a certain someone who really kinda sucked out of the picture, it's really all about being awesome. And a bit about freeing slaves.
It's still all vaguely connected by some big bad trying to take over the world and a bunch of doogooders/mass murderers opposing them.

I haven't played Black Flag yet, because I haven't finished AC3 yet, but so far for me the overall theme has been the same. A lot of people might think that it's 'deterring' maybe because they fell in love with the mechanics in AC1 and AC2 which has (clearly) been removed from later versions. So far I have loved the storyline of the franchise, up until the 4th one (remember, I'm on the third one).
