Despite that the original game was released a long time ago, Chrono Trigger DS is still the best
One of the best things of Chrono is that you can travel through time, you will go to the prehistory, to a ruined future, medieval ages and an age controlled by people who use magic and of course the age of the protagonists. Like all other rpgs you will have to level the characters, and a new gameplay mechanism that was new at the time that Chrono was released is that you can use dual techniques, in other words two or even three characters of the party can combine their attacks for deliver a more powerful one. For the DS you can use the lower screen for make the attacks more faster or move your characters in the minimap, plus you can open different menus.
The story starts as the millenium festival is beginning, Crono the protagonist will be woken up by his mother and then he will go to the festival, there he will meet a girl named Marle and after a while they will be where Lucca, a friend of Crono, and her father are showing a machine they created, Marle enter one of them and then she dissappears starting the time travel plot. There are also more characters that will be at your party like a guy who was transformed into a frog, a robot from the future and more.
Also what made this game famous is that important japanese people helped the game, one of them is Akira Toriyama who created Dragon Ball, he was in charge of the character design (for that reason many characters like Crono has some traits of some dragon ball characters)
The graphics are almost the same as the SNES version but they still seem good, being for a handheld console, the music is great and the replay value of this game is great, there are like nine endings in this game so if you want to get them all then you must do the game over and over again, with a new+.
Overall this game is great and one of the best rpgs out there like I said and despite Square added some new content like monster arenas, they dont seem great but at least are optional so the new content dont affect the game. This game is a must for every DS owner.
