The quests could make the experience less somewhat, they're pretty much fetch quests and too many thrown at you. They do have nice writing in them and you get nice rewards, I think it would be best to play as much as you want and skip the rest for playthrough B when you had enough. But you can't do quests from part 1 on playthrough B though.
The graphics are technically not good but they're functional, the game is more about style.
The game can feel repetitive and probably depending on how many side quests you do.
Also they could have made better use of magic, forcing you to switch between them and make them feel more useful but that's a very minor little con.
The reviewers compare the game more technically with other games and they don't seem to care about its charm, what it's trying to do, its story and localization. It's one of those games you'd have a lot of fun with and get reminded about ps1/ps2 games for some reason. Well at least I did.
