I used to get pretty much every games magazine available every month through my teenage years - Computer & Video Games, Crash, Zzap!, Your Sinclair, Sinclair User, ST Format, Amiga Format, The One, The Games Machine, ZERO, Mean Machines, ACE, EDGE, ST Action...
and many more!
Some mags sprang up and died out very quickly but most I collected for years, and I kept them and re-read them constantly. Into my 20s I started to throw them out or give them away, eventually just ebaying things like the number 1s.
I do occasionally go to ebay and buy a random old issue of something just for a nostalgia blast. A couple of pounds for a warm fuzzy feeling. The best thing is flicking through one of those old mags and knowing exactly what's going to be on each page because I read them so much back in the day
I did dutifully collect EDGE until a couple of years ago, but that was really out of a compulsion because I had a complete set from number 1. Towards the end I literally used to buy it, flick through the pages then add it to the stacks in the loft. I threw them all in the recycling bin and amazingly never regretted it.
The only mag I buy these days is Retro Gamer. Which says it all really!
