The type of games you play should help you determine how many buttons you need. For example, if you’re a big fan of real time strategy (RTS), role-playing games (RPG), or massively multiplayer online (MMOs) games, you’d be we’ll advised to choose a mouse with between 10 and18 buttons—like the Razer Naga Pro or the SteelSeries Aerox 9. These games typically require you to fire off a lot of commands quickly, so the more buttons you have to program commands and macros in, the better. On the flipside, if FPS is your go-to game type, you’ll probably want to keep your button count to between 6 and 8 buttons. Chances are you won’t need the higher button-count for your smaller list of commands. Plus, buttons tend to increase a mouse’s weight, so opting for a mouse with fewer will most likely mean it’s lighter and quicker to move in the frantic FPS action.
