This is probably more a problem with me being unable to find statistics which i am absolutely certain must exist in some form: How many people play with the sound off/on when playing browser games or very casual mobile games. Because in my experience: nobody, but that is too subjective.
The question i want to answer for myself: Is it worth adding sounds to my game. But I dont want to base that decision off of my personal experience (sound is always off), but rather some cold hard fact.
They must exist somewhere, someone must have compiled that data, but I cant find it anywhere...
