I'm also one of the people who prefer CC to CT. Both are great games but to be honest, I never really understood the hype about CT, it didn't really do anything special for me.
Yeah, same here. Chrono Trigger was a really nice game, but I never had any ambition to really complete it or anything. It was a really great game but.. I don't know, it just couldn't suck me in for whatever reason. I still don't understand why.
Chrono Cross on the other hand.. That's my favourite Playstation RPG. I'm actually somewhat tempted to pick that badboy up for my PS3. It had really great style and a fun as hell battle system. I also felt that it had more of a "sandbox" feel than Chrono Trigger. I know you could travel through time and all that in Chrono Trigger, but Chrono Cross definitely had more locations to visit which changed greatly depending on which world you were in (home or alternate).
I can think of a few dungeon crawls in Chrono Trigger that just made me go "Ugh! Where's the end?" But man, in Chrono Cross.. I think the only dungeons I disliked was the Gaia's Navel and the ghost ship. Aside from that, the dungeons were all really awesome and unique.
Also.. Serge > Chrono.
