Snes RPG's are some of my favorite and this feels perfect.
Collecting them and using different combos was a lot of fun. I did find that using any of the summons really necessary. I beat the final boss without using any djinn spells and summons at all. I just equipped them to their respective characters and used their spells and whaled away at the bosses.
Probably one of the best features of this game is the fact that you can load your save data to Golden Sun: The Lost Age. That way when you use the characters again you don't have to waste you time leveling them up again. Not to mention a few actions you complete effect certain events in the second one. I would highly recommend this game to anyone who thinks that the SNES had the best RPG's to date. I know I do.
