So you're skipping an entire game, and all it offers, simply because it lacks the option to walk?
Honest question here - do you suffer some form of obsessive compulsion, or a mania? Because that's not normal... Everyone has different tastes and quirks, but those don't usually prevent people from enjoying different things.
I couldn't play the Witcher without a walk toogle option, many people had the same feelings about it, until a walk toogle was introduced via a mod.
