I'm getting to where I struggle and can't handle fast paced combat games. God of War on PS4 about pushed me to the max. Also Shadow of Mordor which I finally finished. I absolutely detest the artificially added, anxiety inducing unnecessary sound effects such as jumping down from a high place and your character goes into wraith mode and it just shrills this awful sound. The game has way, way too many fairly useless audio ques that drive me nuts. I also tried playing Nioh but the combination of ridiculously fast combat and extreme challenge is probably going to be too much for me. These kinds of things either in part cause or provoke what I think is a certain level of OCD. Hurts the brain and causes so much noise in the mind that its hard to get it to be still and quiet again.
I used to not like them when I was a teenager and in my 20s by now I like turn-based games especially things like Expeditions Conquistador and Banner Saga. Games with lots of storytelling and that don't rush you. I'm really enjoying Ghost of Tsushima. Combat is challenging but regular combat has enough breathing room in it for me. Some of the bosses however like this Ronin duel I just had pushed me to the limit again because they move fast and there's multiple variables going on like unique enemy combat behavior, sound effects, music, cinematic background visuals and dialogue. This game is worth it though.
stay away from rainbow six siege then, its sensory overload as you have to pay attention to any audio cue, call out from team mates, doubt said call out because yo know that character isnt in the map or you just passed through where said call out was, was that background noise or did you hear someone in the cam beside you ? is that footprint leading me to caveira or is she tricking me into a room to gangbang me ? are there valkeries cam in this corridor, do i look up or continue to focus on the door ahead, should i focus on the door or the stairs in front of me......WHY MY TEAM MATES LEFT ME BY MYSELF without saying anything ? oh god they are all dead, its on me now. what are those aproaching footsteps from multiple floor levels ?
