The thing to understand about Legendia is that it is not the best Tales game. In fact, out of the four Tales games I've played, it's the worst. Even so, it's still a good game, and was still better then quite a few other RP Gs
What Legendia's really got going for it is music, background and setting, and just general awesome atmosphere. Go Shiina's music is a different style than the other games, but it fits the new setting, and damn if it isn't awesome. It's my 2nd favorite soundtrack of all time, beaten by Katamari Damacy (dur) and beating Tales of the Abyss and Pokemon Black&White. The scenery is nothing short of Scenery Porn
. (Like this
, and this
. Note that NONE of those are even final dungeon graphics, just plain ole, regular dungeons and town.) Both music and scenery make for a fantastic overall atmostphere.
As for the characters and story itself, well, the story wasn't anything special for me, until it got to the Character Quests, at which point it got REALLY interesting. I liked all the characters, too (although Shirley got on my nerves a few times). But I've heard people profess their hatred for both, so there you go. It is very annoying that there's a severe lack of side quests, a feature I'd always loved about the Tales games.
The gameplay is where things really suffer, though. The dungeons are basically long roads of scenery porn with no real puzzles to play with or landmarks to keep yourself from getting lost with. What's worse is that you'll probably have to trek back and forth two or three times through each LONG dungeon (and they're all long) over the course of the game, with no quick jump. T_T For the battle system, well, it's similar to Phantasia, with a 2D version of the basic Tales battle system. For me, it was bearable at best, since getting special moves was way more complicated then it should've been and almost all spells were nerfed.
Pluses: Fantastic music, scenery porn, and storyline
Minuses: Dungeon length, lack of side quests, and battle system
