Hmmm. Reviews of those were really harsh back in 2005-2006. What are they like? Did you enjoy them? Why did they get so many low reviews?
They're fairly low budget and handheld games in that era were graded on a curve. Lots of great PSP and DS games got much lower scores for simply being on that platform. I'd say that they are enjoyable, but I would only recommend them to fans of the series to play later on. They can provide some history and context, but they're objectively the worst that you can play in English.
Okay after reading a few reviews, they sound a lot like the Lunar games. Decently good for their time, but kind of generic, linear, and a little grindy. I've broken JRPGS up into four different eras. They are...
the 80's era (Final Fantasy, Final Fantasy II, Final Fantasy III, Phantasy Star, Phantasy Star II) IMO games from this era just aren't enjoyable. They are insanely grindy, and basic. Enemies are recycled with pallete swaps. A very basic, and linear town-dungeon-town cycle is present. There's almost no room for freeform quests, or sidequests.
the early 90's era (Phantasy Star IV, Super Mario RPG, Final Fantasy IV, Dragon Quest IV, Lunar I, Lunar II) These games are much like the previous era, but more polished. There's less grind, and maybe one or two sidequests to take on.
the mid to late 90's era ( Chrono Trigger, Suikoden, Suikoden II, Final Fantasy VI, Final Fantasy 7-9, Chrono Cross, etc. ) These games are very open ended, with a lot of things to do outside of the main story. Characters can often be customized to a ridiculous point in battles. Secrets and extra bosses are scattered throughout these games. Some of these games toss the grind to the wayside, and present a much shorter, but cleaner game.
and finally the post FF-X era, which pretty much entails everything after that.
Some developers came into these eras much sooner or later than others. There's some overlap in the timeframes. So you can have a game like FF6 releasing alongside Lunar.
TL/DR: Anyway, I just didn't like the Lunar games, or Dragon Quest 4. These older Legend of Heroes games remind me of that. Also according to RPGFan there are serious translation issues.
