While the Mac's keyboard and mouse ought to be enough for most purposes, having a dedicated gaming controller can give you the feel of playing with a gaming console. If you own a Mac and have a few games you would like to try, then you might also be interested in getting a gaming controller or two up and running with your system. While the Mac platform has not been noted for catering to hard-core gamers, there are still many popular gaming titles and gaming accessories available for the Mac OS.
