there is a reason why the games you mentioned are mostly single player sandbox games and not MMo’s or anything like that.
leveling might be fun for you but it was been a major grip with the comunnity, long leveling feels awful generally speaking thats not what the players want.
samething with the items, there are a lot items because players want a lot way to gear up, nobody wants to farm world every day for months to get their bis.
bad take
