Just tried the gameplay out yesterday - not too bad. Seems like a "port out" than a remake, i suppose. The DS version is making use of its functionality - enable us to choose between the DS mode (making use of the dual screen and your touchscreen feature with stylus) and the Classic mode (single screen - just like the good old days). More game features - to check out maps, monster's stats and treasure - better modification than the original SNES platform in the 1995.
Character-wise remain the same with Crono, Lucca and Marle et al. But, what i heard was that there will be one extra ending to it... because a new dungeon is being included in this DS version. Not too sure about that - since I am only one hour into the gameplay.
Everything just look to be nostalgia to me with the old Chrono songs and the character designs, plotlines etc....
But I guess this should be one of the classic games that the nintendo fans will remember and love!!
