Phantasy Star isn't top 100 in a list of console games from 1977-1987? Are you anti-RPG, or do you just not like PS that much? To each their own though. You are entitled to that opinion, I'm just stunned. While not console, what do you think of King's Quest if I may ask?
As for Ys, I don't see how it's that overrated, since it almost never makes the top 10. If anything it's very overrated. I put the early 90's Ys: Book I and II on the TG-16 CD-ROM as number 1, ever. The 80's SMS is not close, but I liked it a lot.
