I demand you fix the title of this thread, right now.
hows that.
Ah, I can breathe out now.
Ys 1 & 2 by far the best in the series. PCE version amazing, PC Ys Eternal amazing, yet somehow missing some of the dramatic feeling of the PCE version which is odd.
Ys 3 is an odd one, but the music makes it great and it's still hugely addictive and fun.
Ys 4. I'm still playing through the translation and I'm finding myself in agreement with you. There's just something missing - it seems more like a constant grind to the next area than a story. I'm actually considering downgrading the rating on my site.
Ys 7 was decent, some nice references to the old ones, but lacking in a really compelling story I felt.
Oath in Felghana is brilliant purely because it expands and fills in the Ys 3 storyline, making it much more interesting.
Ys Origin is very very very very awesome. Although it's almost a remake of the original Ys puzzles, the story is fantastic as it fills in a lot of history - and you have to play through as every character to really get the most from it. Fact is real fun, almost like playing a shooter.
