In recent years, I've definitely felt Dragon Warrior (I refuse to call it Dragon Quest, just the same as I refuse to call Princess Toadstool "Peach") is a far better series than Final Fantasy from a gameplay standpoint.
Dragon Warrior on NES I used to have a pretty love-hate relationship with. I didn't beat it until only a couple of years ago, and since then I've really fallen in love with it as a game. I'm really hoping 7's 3DS remake makes its way over to North America.
My only gripe with the series is the re-translations on the DS are awful. Silly puns aside, the unnecessary need to give everyone an accent has caused me to unfortunately skim through the games' scripts. I love listening to Irish and Scottish dialects, but they do not bode well in phonetic text. I'll take Dragon Warrior's Elizabethan over that cumbersome shit any day.
