I got rid of all my old PC Gamer mags several years ago. The only mags I held on to for a while were issues of Next Generation. I ended up getting rid of those after a little while longer. Funny thing is, I started thinking back to Next Generation (as a good industry magazine, at least coving the topics more than just being a mouth piece for the marketing departments for publishers) and wondered if anyone had scans of them online.
After doing a few searches, I found a guy in my town that was trying to unload a LOT of issues he had from his subscription days. I contacted him and he still had em. I drove over and picked them up. I've had a blast re-reading (and reading the ones I didn't have before) and taking a look back in time at the industry. Many issues then are STILL issues today...movie games that suck, game movies (films) that suck, violence in games, etc., etc.
I didn't get every issue, so I've tried to find the last few of them to complete the collection. I'm currently readin the issue from March 1999 leading up to the launch of the Dreamcast (one of my favorite systems). It will be interesting when I get to the Playstation pre-launch time and see what smoke and mirror tactics they were using then (like now with the PS3...lol).
I say if the mags are just fluff articles with reviews/etc. you can probably get rid of them without any real big regret. However, if you have a sentamental attachment to the mags (or games they cover), or, would like to go back and re-read some of the info, then hang on to them. We actually have a magazine rack in one bathroom with some old gaming mags just to flip thru. :}
