Greatest. Game. Ever.
Everything about Chrono Trigger is excellent, from the music to the visuals, to the EXTREMELY unique gameplay (Hell, it introduced the new game + feature), to the characters, to the plot, to the bosses, etc.
Just the whole concept of the game is a nerd's wet dream, with music by Nobou Uematsu and Yasunori Mitsuda, art by Akira Toriyama, Yuji Horii was the scenario writer, and the game is designed by Hironobu Sakaguchi. Truly the greatest dream team ever assembled in the realm of video games.
Get it on the Wii VC, get it on DS, get it on emulator, (if you are REALLY patient and don't mind loading times much) get it on PSN, and if you're a real hardcore fan like me, get it on SNES. Funny story: I actually have owned the SNES cartridge since day 1. That's how cool I am 8)
Also, the only possible problem this game could have is the fact that it's kind of short for an RPG, but that's made up for because
1) You'll NEVER have to level grind
2) If you use new game+, you could get about FIFTEEN EXTRA ENDINGS.
This is truly an even better game than even the likes of Final Fantasy 6, Megaman X, Link to the Past, Earthbound and Super Metroid; I give it an 11/10.
