While I understand that FF7 had a lot of hype for it's release, I played it way after the hype train left. But I kept an open mind about it and to be honest, I think it's a good game but there are many others that I enjoyed more. Personally, I think Final Fantasy games are overrated, the only ones that I really liked were FF6, FF9, and FF12. But I think story, atmosphere and gameplay were more interesting in games like Persona 2, Chrono Cross, Fire Emblem: Awakening, Pokemon RSE, Dragon Quest 6/8, Xenogears, Parasite Eve, Suikoden, Shin Megami Tensei: Nocturne.
Again, I'm not really a big fan of FF and I did like FF7 but to say FF7 is the "best RPG" isn't right. It's all based on opinion and to say anything is the best is stretching it.
