[IGN PRIME] (sub) Big Day

Hell no, half time they just skips months for no reason. You do not get it for games.

in 2013 there was a small glitch( or promotion), it was possible to issue a permanent IGN Prime subscription for free...
many users have kept their old Prime subscriptions

I subscribed for a month in October 2014 just to get Endless Legend. The game had only released that September so the $5 I paid for it was a spectacular deal. I immediately cancelled my subscription but have continued to receive all the Prime benefits since even though IGN had previously claimed to have fixed the bug that made that possible. For me just the $5 for Endless Legend was excellent value, everything else has just been a bonus. None of the games since have even come close to that though and I'd say it was only worth a temporary sub if another particularly good deal game along.
