My memory on many things has been going south for some time, but as far as visual memory, that's always been somewhat better for me. It CAN take a try or two to get a nav route to a mission in my head when I'm doing a video walkthrough, but overall visually my brain works much better. I also seem to have a knack even when off capture to usually pick the correct route when objective markers aren't there to help you. It doesn't mean I don't get disoriented and lost in some games at times, and I really hate when that happens, but usually it means I've been up too late with an ultra long session, and when I fire the game up the next day, I find my bearings right away. It happened just yesterday when the night before I was trying to find the last few statues in the Paint the Town side mission in Far Cry 6 after beating the game on Guerilla mode. I just wasn't using common sense, I was overlooking the sewer system basically.
Now I'm having a go one last time at Far Cry 6, again on Guerilla mode, but with all HUD elements off. I only have the map and weapon wheel. It's been pretty interesting so far.
