The original AC games were really great for their time, and to be honest I enjoyed the ones that came after the trilogy despite feeling like the same game with a new coat of paint over and over.
But they really knocked it out of the park when they overhauled all the controls and mechanics with Origins, Odyssey, and Valhalla. Yes, there are issues with them like with every open world game, but it is really worth checking out. Valhalla is obviously beautiful and very refined but I favor Odyssey for the sheer fun factor.
Agreed on these new ones, though.
