New gimmick? Are you kiddin me? Those gimmicks are fucking pathetic and never justified all those sequels they made. AC(new and fresh game), AC2(lots of new stuff and improvements), AC3(added guns and murica, if you into that sorta thing), Black Flag(improved the one thing everybody liked from the last game). Literally those are the only ones that should exsist and even that is spreading it a little thin. All others are basically worthless excuses of charging full-price.
I quess yeah, we are taking their work for granted. Voice acting, making new cutscenes and new stories is not easy. But the core gameplay is exactly the same it was back in 2007. They have improved on it and added a lot of gimics, but at its core its exactly the same. I am so sick of its artstyle, parkour, animus, stories, weapons and combat. AC quite frankly just disgusts me now.
