BEEP Megadrive is an old magazine. There was also FLash Sega Saturn which came w/ demo discs. Or maybe Flash was just the discs... can't quite recall. Those were dedicated to that system only.

Famitsu XXX is mainly dedicated to XXX but will cover some other stuff for a few pages from time to time. At least a couple of adverts in the back or something.

Generally, Famitsu is the most popular, although sometimes the free stuff gets lame. Dricas (Dreamcast) Magzine was good. Came with a demo CD w/ about 7 demos on it each quarter.

I've not bought a game mag in months... they generally just tend to take up space after you flip through them once.
