Yeah, me too. As we age, struggles with health issues just keep getting worse. Welcome to physical incarnation.
No experience with hunting games genre, let alone slow moving ones. Perhaps explore some other non-FPS genres? Many videos on Youtube have lists of reommended games to check out.
But yeah, same as you, also fussy with which games to buy and play, afte previewing hundreds of games on youtube, but still don't want to commit to buying any title right now. It can be exhausting gettting used to the UI and controls of each new game. Ruins the joy. Not to mention unless it's on a big discount, most games are overpriced these days.
