I was a little late being a subscriber to these guys, so I missed the era of using Nintendo Power for cheats and such, but I loved it for different reasons. The sense of humor these guys had was great, always a ton of in-jokes and funny features. I always liked reading the section where people sent in letters, because the editor who responded always had something silly to say, and there were always people sending in their crazy Nintendo creations. I also used to like the art section immediately after that.
I definitely noticed an unfortunate decline around the time Future became their publisher. The price stayed the same, while the magazine itself got smaller and smaller. I ended my subscription probably 4-5 years ago. I ended up giving most of my collection away to good will. I kind of regret that. It'd be nice to have a big collection throughout the years, just to read all the old news, and the articles that will be long forgotten, not like on the internet where everything is archived, these magazines will be unfortunately forgotten too soon.
I might just have to pick up their last few issues, just for old time's sake.
