I loved the original Chrono Trigger. I beat it over 3 times with the new game + feature, and because of that feature and the fun story, and game play that didn't really resort to grinding too much.
That said, I don't see myself revisiting the game again. Mainly because, I don't want to go through beating the game again without all my levels I earned and items I found. That being said...I never did get to beat the game on the two hardest times to beat the game. (The very beginning with just you and the girl, and that time you had to fight the cult and the final boss.)
