I can really appreciate how awesome Phantasy Star is, as I am currently playing it.. I really like the animations of the enemies, in the pseudo FP Battle system. I do also like the dungeons, but they could use a bit more, they get overly confusing because they all look identical except for color, few more landmark type features would have been helpful so you could at least tell which hallway you were in.. I'm not really complaining about it tho, the gameplay is awesome. Not a lot of time is wasted either, I like how you're in & out of battles fairly quickly, except for the opening a chest after every battle... Grr.. All in all, it is fast becoming one of my favorites..
As for Dragon Warrior, I am enjoying it equally as much. It is way more similar to FF, but they single character feature is bit annoying, but at least you're only forced to face one enemy at a time. I've got about 10hrs into both games as of right now, spent a lot of time grinding in both games, so I don't know how far I am actually thru the story on either one.
Depending on how I am feeling at the end of PS, I may play a rom of Wizardy next, unless I can track down a cart first of course I've been hearing really great things! Console wise, I think Ultima Exodus may be next.
