Speaking of VIII, I got my hands on a PS2 copy not too long ago (would have gone with 3DS, but it was nearly $50 cheaper just to get it on PS2). What's interesting to me is that I can see the genesis of a lot of ideas that would get fleshed out more in XI. Most notably there's the alchemy pot, which is a cool idea and it has more of a puzzle element to it, though I personally prefer the Fun-Sized Forge. There's also the skill points, which I flat out think was done better in XI since there's no way of knowing which skills you should upgrade on a first run nor will you know what weapons you'll end up with unless you know ahead of time.
On the whole though it's really good. I like the characters, and the smaller cast gives them more time to shine. As much as I love XI's cast, some characters kinda drift into the background. I especially like that the game has you actively chasing Dhoulmagus as opposed to other games which have the antagonist sitting in an evil castle somewhere. Maybe that will happen, I don't know, I just got the ship, but it gives the early game a sense of agency. I also like how the world feels so vast; the overworld feels like classic Dragon Quest transplanted into 3D, and there are moments where it's absolutely breathtaking.
