The game is over 30 years old and pioneered a genre. Pretty sure Final Fantasy and Dragon Quest 2 were some of the very first to feature a party of characters instead of a single protagonist.
Objection!
Final Fantasy was released in December of 1987. The three main video game influences for it where Dragon Quest and transitively Ultima and Wizardry. As you mentioned, Dragon Quest II featured a party of characters and was also released in 87 (January). BUT Ultima 3, the first of the serie to have a 4 character party was released in 1983 and the first Wizardry already had a party back in 1981!
On a side note, for me what differentiate japanese RPGs from western ones is characters that are blank slates or not. This differentiation still does not exist in Final Fantasy I and Dragon Quest I, but is definitely there by Final Fantasy IV and Dragon Quest III. Quid of FF II and III and of DQ II?

I am playing the WonderSwan Color version. To bring the video game hipster factor to 11, I don't have any WonderSwan Color, I have the special
Final Fantasy branded edition! To be fair, the thing was extremely cheap at the time. I want to say it was something like $100 for the pack with the console and FFI. There are some minor quality of life improvements compared to the NES version, but I also get 16-bit pixel art, backgrounds in battles, shops you can walk in, and some cut scenes, both of the "digital puppetry" kind we know and love with the standard game view and the characters that move around and react and, more surprisingly, some full screen cinematic ones (notably for the explosion that opens the passage between the sea and the ocean).
EDIT: Oh and that's a second attempt at a first play through (the first attempt being the 6 hours I played in 2000), but I am not very patient with this type of games, so I am using external resources as soon as I am somewhat stuck or confused about what something does, etc...
