Surprisingly, this is my first time playing Dragon Quest 3 (Switch, also on GBA, SNES)
Yes I know, jrpg, chibi, grindfest, etc, etc. -- BUT! For some strange reason, I have serious early Ultima flashbacks playing this little gem.
Aside the graphics and overall themes, the game is fairly "western-ish" and surprisingly complex: you have a big overworld for non-linear adventuring, lots of optional side quests, impressively flexible party system, and even a Lord British imitator king for good measure!
Heck, this is the first game where I genuinely enjoy grinding.
If you dislike jrpgs, because for reasons, try this one out -- you might be surprised (even so, considering the age of this game!)
