Your scans are a bit large lol.
Anyway, late 80s/early 90s era UK magazines were fantastic.
I still have the complete set of Super Play, all of Davies era CVG, Maximum, a lot of Official Sega Saturn Magazine, Mean Machine Sega, N64 mag & NGC mag.
And a few odds and ends - the tips mags like Super Gamer and so forth - I have one with complete mappings of the Sonic 3 levels which was priceless for those hard-to-find super rings, and I also keep the uber-goofy late issues of TOTAL!, when they had guys like Danny Wallace there. And issue one of the ill fated Mean Machines Playstation.
Retrogamer will be a future one I will keep for the fantastic features and so forth.
Basically I just keep stuff I would want to reread at some point. Even edge isn't worth rereading apart from the olders ones with the biffo columns really.
As for my favourites:
Official Sega Saturn Magazine - Best "official" mag ever. Really well written, enthisastic coverage . Once had disc one of Panzer Dragoon Saga free with one of the issues.
Super Play - This got me into JRPGS. I'd played a few on the NES, but SP had some fantastic import coverage on the genre, so really got me into importing games from other regions too. Didn't even have a clue how to do it before Super Play.
Maximum - This didn't run long (Was a "next-gen" focused magazine that came out at the beginning of the 32bit era). The layout was incredible, whoever did the graphic design for it was great.
CVG - Before Paul Davies was editor, CVG was an average magazine. After Paul Davies was editior, CVG was an awful magazine. But WHILE Paul Davies was editor, CVG was
the best video games magazine there has every been. He assemebled his own team, and totally changed the look of the magazine. It had fantastic writing, a pull out section with coverage on arcade games (printed on special paper that was designed to give a cheap "fanzine" look but was more expensive then the main magazine!), and brought in an out of 5 system, arguing that out of 100 was pointless.
