I agree with you. Even though they’re still not the kind of game so would play regularly, Overwatch 1 was extremely annoying to play with all the stuns, freezes and more. Overwatch 2 toned down and removed most of these which made it actually somewhat enjoyable.
AC3 is kinda infamous for not being great but I think it was thematically the strongest. It just had a ton of pacing issues. If you liked AC4, I suggest playing through that to see Edward’s legacy in a different light. Or read the AC3 book which tells the AC3 story from a different perspective from Edward’s son, it also documents everything that happened after the game.
