Well, this game is easy to review: perfect.
Chrono Trigger was made by a team they call The Dream Team. SquareSoft got all the best game makers in the world together and told them to make a game. That's why every aspect of the game is perfect, it was made by the best people available. If God decided to make a game it would be exactly like Chrono Trigger.
I really don't think that I game of this standard will ever be made again.
