Both games are amazing (two of the best RPGs of last year, any platform), and you should really get the both as well as the upcoming
Ys I and II Chronicles ...but if you're only getting one,
Ys Seven is the one you should get (going by the gaming media/message boards will probably tell you otherwise, but I've learned a long time ago that the gaming media and message board dwellers who follow them are ALWAYS wrong about every subject that's commonly discussed - it's just a matter of what degree that they're wrong).
Ys Seven is a better game w/ far better "Premium Edition" contents...but again you should really get them both.

Ys Seven is hands down one of the best RPGs I have ever played. The story, world, and characters had me attached immediately. The soundtrack in this game is also the best soundtrack I've ever listened to in a game, period. I can't stress enough how amazing this game is. It is a 30hr game and I pretty much played it straight through over a 4 day period...I just couldn't put it down. If you only have enough to grab one, grab Seven as it does everything right and knocks the socks off any other RPG I have played in a long time.[/QUOTE]
I agree. Definitely the best RPG of 2010 (any platform), and hugely underrated.
The only really thing I hated was the bad dialogue (Oath in Felghana is even worse - most grammatical errors I've seen in a recent game), but that's because piss poor translation - nothing to do with the developers.
The story itself in Ys Seven is one of the better ones in a JRPG.
