The whole point of designing them well is to curtail possible frustration, to limit the kind of problems that might cause genuine exertion, or to always provide alternative pleasures if certain ones are difficult. It can be, of course, a wonderful feeling to be in worlds like this. There are so few ways to miss that feeling of accomplishment-induced pleasure. It doesn't matter much how artificial that accomplishment is: the pleasure it causes is very real.
