I personally didn't like FFVII too much.... You really had to play it when the graphics were considered 'cutting edge' to fully appreciate the game. I'll always favor FFVIII from the Final Fantasy series because it was the first one I've played and, not to mention, it had a great story line and awesome cut-scenes.....
You always debate what the greatest game of all-time is, because, everyone has their own personal opinion. Looking at it with a non-biased perspective, The Legend of Zelda: The Ocarina of Time is a good competitor for greatest game of all-time because, at the time, it had great graphics, break-through game play and an awesome storyline. I haven't met a person who has played that game that didn't like it.
