Last year, I took a look at X-Arcade's premiere product, the two-player joystick. It demonstrated X-Arcade's quality as a brand and attention to detail. Since then, X-Arcade has introduced a new product, its Trackball. Designed to look and feel like ball-based arcade games from the past, the X-Arcade Trackball fits the bill. With a 3-inch-ish ball, and a rolling action that simulates the "I'll take a beating from a bunch of 80s kids" feel, playing with the trackball is actually great fun. And it features the exact same parts and feel as the other X-Arcade controllers. I has USB and PS/2 connectivity so it is a great choice for any computer or MAME system.
