Zelda II: The Adventure of Link is a game full of good and bad qualities. One can argue as to whether it's a good or bad game (that is, after all, subjective), but one cannot credibly argue that it's not a significant departure from the first game. Were it a new franchise and not a sequel, it might have received more praise.
Chrono Cross is very similar, and I sincerely doubt I'm the first to compare the two. Some people really like it, and there's nothing wrong with that, but I am 100% biased against it due to overall style shift from Chrono Trigger and the lack of character focus. Were it it's own separate entitiy, I might be kinder to it, but I dislike the story and how it continues on from Chrono Trigger, and it's impossible to separate those feelings.
Granted, it's not as though I should feel obligated to try and separate. We're talking about a video game. The world does not stop turning if I can't appreciate Chrono Cross as its own thing, and it shouldn't stop anyone who does like it from doing so.
That, and new content for the DS release of Chrono Trigger further connected the two games, so I'm going to proceed to be "BAH!" about it.
That said, I would definitely like a spiritual successor to the original Chrono Trigger with a similar style and mechanics. Also, I like about 80% of Zelda II. B-, Nintendo. Good job given that it was an era of figuring, like, EVERYTHING out.
