I don’t have any RPGs played on it. I haven’t played any in a while. What makes these games you’re speaking of so hard? Why can’t you just grind to win?
I don't know about those games specifically but quite a lot of games actually have level caps so once you hit that maximum you can't get any higher. Late game bosses can often change depending on your level too. Beyond that I'm not sure.
