Chrono Trigger (クロノ・トリガー Kurono Torigā) is quite possibly the best RPG ever made. It came out in 1995 for the Super Nintendo and was later re-released for the Playstation and then on the Nintendo DS a few years later. You know a game is incredibly epic when it has to be released not once, not twice, but three times!
Squaresoft created a "dream team" which was composed of Hironobu Sakaguchi, the original creator of Final Fantasy, Yuji Horii, and Akira Torimaya. The musical score was partly created by Nobuo Uematsu after the original producer fell ill.
Why is this game so great? It is a combination of all the aspects of an RPG that make it successful. An incredible storyline with characters that develop, interact, and grow alongside a vast world. A terrific battle system with cool combos and tough boss battles unparalleled by current games today.
The awesome part is that you can play this masterpiece on nearly any device today. If you are lucky enough to have a super ninendo console, you can enjoy playing it there, or if you have any newer generation mobile phone, PSP, DS, etc. You should be able to emulate it there!
