Designed from the ground up with MMORPG’s in mind, the Rival 500 is SteelSeries’ best foot forward. With a top of the line optical sensor, it matches any top end esports mouse made for even the most intense games. The real things that set this mouse apart are the 15 programmable buttons, tactile alerts, as well as the heavy weight and bulky shell. The mouse is not only more suited for MMORPG’s because of the amount of buttons, but because it is also one of the heaviest mice on the market. While this can work very well for certain types of games, fast paced FPS aren’t quite suited to a mouse of this size, and RTS players would also likely struggle to move around as fast as they may need. Tactile Alerts also benefit an MMORPG player, as they can set the mouse to vibrate at certain intervals (like when their cool-down is finished on their favorite skill). The MMORPG market doesn't have many good mice built specifically for it, but this one is tried, tested, and one of the very best you will find.
