I sometimes bought Retrogamers special issues. I think now apart from exclusive interviews there is better information on HG 101 or even paper scissors shotgun not to mention a plethora of YouTube reviews and retrospectives
Certainly there are better, more in-depth resources of information to be had on the Internet about this (the current website I'm reading is 'Games That Weren't' and the discovery of a fishing game Ocean did for the TV show 'Dramarama') and listen to the Retro Hour podcast at work as they do conduct some excellent interviews.
One of the main reason why I buy Retro Gamer is that I'm not stuck reading a screen all the time as this way it's better for my eyes and mind . The interviews are good and there are some interesting articles about the making of games (do enjoy reading the 'Conversion Capers' segment about them).
