Unless you are a hardcore gamer, you don't need a gaming mouse. If you play casual games, then a normal mouse is perfect for that. But, if you play long session games, then we strongly suggest you buy a gaming mouse. See, a gaming mouse is made for a purpose. It offers a much more comfortable experience, stylish look, and more settings. So if you play a lot of games, then you need a gaming mouse, but if you play casual games, then you don't need a dedicated gaming mouse.
