The day I beat Shining Force in 1993. I had never beaten a real RPG before. So, not only did I enjoy the journey and the story, but getting all of the way through to the end was my great moment in video game history.
Back in the 80's, when Atari was king, one could find video games in just about any store. I remember games in every store I visited. I bought my first Atari game, Human Cannonball, at an old Medi-Mart, and saw some behind the counter at many Osco Drug stores.
