How much wiggle room is enough will obviously vary a lot by player, but I do truly find the older Souls games to have much more of it than people realize if you play smart. Even a little too smart in some cases.

But I feel you on the carpal tunnel. There are a few rhythm games I enjoy, but I can no longer play them on a moderate difficulty for more than an hour before the pain starts - and it takes a couple days to settle down again. I basically have to play on the lower difficulties or not at all. It was a sad day when I learned that.
