Some parts of the game require manual dexterity. Not every player here is a teenager with an X-box.
I don't mind if I miss out on some areas of the game because it takes me 10 times (or more) to do jumping maneuvers that 'normal' players can do the first time with no issue. But for little "required" things like the "Summer's Day" stuff, which you cannot put off because when you try, *every* floating vendor bugs you about it, and when you go in, there is no way to skip out, it can be a living hell.
If there is anything that will make me quit this otherwise awesome game, it's things like the "Summer's Day". Please recognize that just as the game should be flexible to make it fun, so should the game play itself. Some of us are folks with arthritis in our hands (or, perhaps, have other dexterity issues) who like video games but don't like being stuck making the same jumps over and over again because we just do not have the ability.
