maybe we'll just snicker a little then
seriously though, i stopped playing chrono cross about halfway through recently (admittedly, it is my 2nd if not 3rd time through, but still), and after seeing how CE introduces elements of the CC story (bad pun, i know), it actually makes me want to finish the game again. this all to say, CE actually strengthens the CC plot by making it less of a wild tangent off of the original CT storyline, and instead more of a legitimate "aftermath".
so what i meant to say i guess, is by the relative strength of all three storylines supporting each other (four if you count radical dreamers), then there is room for another sequel for sure, it's just that it would be easiest to do one directly following the events of CE, perhaps in a way that further bridges the gap between CT and CC.
all this to say that CE is not just good, it's inspiring ;D
