Sailing the Blue Skies since 2001.
Chrono Trigger (SNES, PS1 via Final Fantasy Chronicles, DS)
Update - My wife was sweet enough to get the DS port for me on Valentine's, and I've been putting it through its paces. It's an excellent port, with smart DS implementation for shortcuts to the menu, a map, and moving the battle details to the bottom screen, freeing up the top screen to see the whole battle. I've dove into one of the two new dungeon areas in the game, and for the most part, it's fun. Unfortunately, it's kind of a giant fetch-quest situation, which is okay for a bit, but does grow a bit tiresome. It's a mild complaint, though. All and all, it's well worth picking up if you want to find out why Chrono Trigger is so highly regarded.
Lo and behold, Chrono Trigger has climbed up by leaps and bounds. My recent play through blissfully reminded me of the joys I held when I first played it long ago. The music is amazing. The character development is deep and well translated (there's a few typos, but nothing too bad). The battle system is classic and still excellent in this modern age, with plenty of magic, techs and combinations to be learned. The graphics are topnotch for the SNES. The storyline is still amazingly solid. The character design is certainly some of my favorite work of Dragon Ball Z creator Akira Toriyama (sp), with strong, likable personalities attached to great design work (Dragon Quest 8 has some good character designs too, btw). Plus being able to plow back through it with your last game's stats is a nice plus. An engrossing, delightful RPG that stands as my favorite outside of Skies of Arcadia and Tales of Symphonia, this one should be in everyone's library somewhere. Square's finest hour, in my opinion.
I picked up the PS1 version to see how it differed. Pluses are the new movie animations (which are for the whole well done, but the quality is a bit spotty...it is a PS1 disc, after all), the sound test options (considering how awesome CT's music is) and more unlockables once you beat the game. The downside is the disc format, which adds several load times into the game that didn't exist before. Getting into a battle? Loading. Pausing into the Inventory menu? Loading. *sigh* I can't really recommend it, unless you're the REALLY patient type (and lack a DS, which features the extra goodies the PS1 version offered without the loading issue...and the anime sequences look better, too!).
