Assassin's Creed has a massive amount of games. There were annual console releases from 2009 to 2015 and several portable spinoffs that were pretty good. There were some mobile games as well, like the Java version of Assassin's Creed 3. So pick your favourite games in the series.

for some reason I dislike assassin's creed 2, I even liked brotherhood, revelations and 3 more.

I've only played AC2 and Brotherhood so far, but unlike most people I prefer Brotherhood to AC2.
