Hardcore gamers need good gaming mice, but tournament-level players have even more specific requirements. If you compete on a professional level (or want to), the MadCatz R.A.T. Tournament Edition is a lightweight, accurate mouse, although more casual players might find its design a little too outlandish. The R.A.T. Tournament Edition, which will launch in Feb. 2014 for $80, does not look much like a traditional gaming mouse.
