Is it worth playing again? Eh, maybe. Is it worth playing a first time? ...Wait?! YOU HAVEN'T PLAYED THIS GAME YET?!
Yes, I'm one of those fans. Beat it 50 times. Got everyone to Lvl **. Got all the techs, items, weapons, etc. Finished every side-quest, mini-quest, ending, you name it, whatever. The thing is I did all this at least 50 times over in the past decade +. And surprisingly, the first 49 times it still felt fresh.
Now that's a lot to say for any game. Most bore me before I'm barely half-way through, but CT is engaging several times through. But not forever.
As my obnoxious summary at the top implies, if you haven't played this game, it's worth trying, no matter who you are. If you hate RPGs, CT might change your mind; it's that good, even today. Or hell, maybe some other RPG won you over along the line and this one pales in comparison. That's fine. Regardless, this may not be as life-altering to you as it was to me, but it will still be a fun ride for one playthrough. I [almost] guarantee it.
Okay, that's covered. Now if you're like me, well, there's another story. Squenix knew what they were doing though. They added just enough new content to bring me back. And I did come back, against my better wishes. There are a few added story elements that clear up what happened between CT and its sequel, Chrono Cross. These kinds of things I live and die for.
Even then though, they are somewhat minuscule and actually quite underwhelming. They even open up new, even more annoying questions! The other added features besides those are really poorly made and placed. The monster arena is so difficult, random, and tedious it's not worth any of the trouble. The Lost Sanctum is an epic fetch quest. Back and forth. Barf. Back and forth. Barf. The optional stylus controls aren't even very fluid! But that's fine because I don't use them anyway.
...And yes, the new story elements and the extras menu are pretty nice.... but not nice enough.
So, if you loved Chrono Trigger on SNES as much as I did, I know I'm not going to stop you from buying it, so I won't try. But it's not overly worth the 30+ price tag. Yes, I know you're not listening.
If you haven't played this game yet... I mean, why haven't you played this game yet?! Are you the most deprived human being on earth?! Yeah, you might be.
I kid though. My final point: Chrono Trigger is a game meant to be played; several times even. Just don't overdo it and go several... thousand... times like I did.
