1 Dragon Quest VIII: Journey of the Cursed King
Best music, best gameplay, best visuals, best story, best characters, best...well...Everything!
2 Dragon Quest V: Hand of the Heavenly Bride
It's so good, it's the focus for the DQ movie!
3 Dragon Quest IX: Sentinels of the Starry Skies
Almost perfect, the one thing I don't like though is how your party members don't have personalities
Great story in my opinion
4 Dragon Quest III
5 Dragon Quest IV: Chapters of the Chosen
I like most of the characters, and the gameplay is fun. It is a bit on the easy side, but if you want challenge the post game bosses are pretty tough
6 Dragon Quest VI: Realms of Revelation
7 Dragon Quest
8 Dragon Quest XI
Obviously the best
9 Dragon Quest Monsters
10 Dragon Quest II
11 Dragon Quest VII: Fragments of the Forgotten Past
12 Dragon Quest Monsters: Joker 2
One of the more unique games, has better graphics than the first and is still a great experience. Highly recommend this for anyone. If you do play this though, you will have to sacrifice a lot of your life to grinding. The games difficulty comes from the grinding but its still fun and enjoyable.

The slime is so cute I'll pet him/her.
