OMGH! lolz! Crono and ghang getz kidnapper$!!!!1!! MARLE T0 TEH RWESCUUUUUU!
Seriously. It's been done before, like with Mario Bros and Zelda. If Peach gets kidnapped so many damn times, and finally Mario AND Luigi are captured along with all the Toads, how the hell could Peach save them?
Marle, while she's good, she would be nowhere near good enough for the whole "Crono & co. were kidnapped and she has to save them" act. Crono is the only character amogst any of them who has the capability to do such a thing by himself. Any of the others would be a no and Marle being best as a healer would make it worse. Not to mention who could actually kidnap them all AND has the mindset that they want to do that?! It's more of a kiddie idea and knowing Chrono as a series, it's more likely they'd be killed. So to have them be simply kidnapped by let's say Lavos who wouldn't even think of such a thing let along be able to move and do so and has no minions to do it for it, wow...
If they ever did such a thing - I don't know. I really don't know. If they made the whole cast Pandas I could handle a game as bad as that but if they ever went with this as an actual idea, that might seriously test how truly strong a Chrono fan I am. I probably would still be a fan but I'd be highly disappointed.
THAT is the worst retcon.
No wait, same thing, BUT WITH LEENA TOO! No other CC characters, just Leena!
