Growing up, I was quite brand loyal with occasional dips to other magazines if the freebies were any good.
ZX Spectrum - Crash magazine Atari ST - ST Format with semi regular copies of ST Action depending on the demo disks. PC - PC Format. Dreamcast - The official Dreamcast magazine, it was the only one with demo CDs. GameCube - I honestly can’t remember which magazine but I definitely bought one regulary.
By the time I had the first Xbox, all reviews and news I was getting from the internet.
