Video games, believe it or not.
Before working, I would just look at the available games that were on sale and just pick the ones that I found interesting and for the most part, it had served me well. When I was able to buy magazines and later a subscription, I was able to learn about all kinds of video games that I had missed out and were regarded as must-plays or part of an awesome series that was still in production. Some of these games included:
*Any Vanillaware titles
*Shin Megami Tensei series, specifically the Devil Summoner series, the Persona series, and Nocturne
* Xenosaga series
* .hack series
* Tales series
