You can tell quality miles away. It is not so subjective. For instance, you may have played GTA5, you may not be a fan of the game, but you would find it hard to dispute its quality. Production values. Same for the App Store, tennis champ returns. I'm not a strong fan of tennis but it is easy to see its a quality game. Same for plants vs zombies. When you use an iPad, you can tell the difference between that and a $20 tablet. Is that subjective?
