The Gameboy Final Fantasies have been announced for Switch. I know they aren't true FF's but were they any good?

They were okay at the time of release as RPG selection wasn't very diverse then. Legends 1+2 / Saga 1+2 didn't really age well though since RNG level ups really can kill your experience, as well as durability weapon systems can cause a soft lock of your game if you aren't careful (running out of weapons and abilities to use). There are a lot of underlying mechanics that will make you scratch your head if you're unfamiliar, especially the monster meat system if you choose to go that route with one of your party members.
It's sad they didn't choose to localize the DS remasters of the very same games that were JP only - instead choosing to just re-release with one or two extra features that don't seem to game breaking.
With the above being said, Legends 3 / Saga 3 is the most traditional JRPG of the three games and would probably be worth playing if you are looking to try out this classic trilogy though I personally wouldn't pay more than $20 USD for the entire thing, if even that.
