This might be jumping the gun but the game has a lot of replay value if you want to finish things. First, the scaling allows you to minimize on encounters until you level up Diablos' no-enc, thus making all the bosses easier. Or you can grind to 100 and max out stats using the card game feature + the +stat purchases

The story is very tedious and silly - I don't know if it is supposed to fit some sort of uber kawaii japanese stereotype that was the style at the time, but I couldn't relate to anybody. Ugh

But yeah, try playing it. It's fun, and Zell has the best / strongest limit break in the game.
