Well I haven't let my Nintendo Power sub expire and it's been active since issue #1. It's also set to run until 2016. According to Nintendo (before they sold off the Future, I was listed as their longest subscriber. I'm not sure if that's true or even if I should have made that public.

I was subbed to OXBM Until the 100th issue. Since my 360 RROD I thought it was time to let that die as well. So Oct 2011 was my last

Again I started with the Buyer's Guide and subbed at issue #1 so I stuck with them al along and am still subbed, though I don't know if they are still sending printed issues.
Retro Gamer Magazine
I'm a sucker for their interviews and stories of classic games.
A tip for people in the USA. Subscribe withe the code YOUTUBE and you will get 13 issues for about $85. Just beware not to auto renew since they will jack that up to $120! Instead subscribed 2 months before your sub is up, contact Imagine customer service (they rock!!) and tell them to tag the new pId subscription on to your existing account. Of course now that I made that public they will probably "fix" that and I screwed myself out of a cheap renewal.
Hmm...thinking of what else.

They promised more issues eventually, who knows??

I think they went PDF only
I tried to sub to the new GameFan, but I honestly couldn't no matter how much I bugged them!! Not very good marketing if you ask me.
And I think that does it for now.
