While I like Final Fantasy 6 just a teeny tiny bit more in the gameplay department, Chrono Trigger is still the pinnacle of SNES RPGs. It has one of the best stories in a video game ever, graphics that really reflect the art style of the character desinger, and revolutionary for the time features like New Game+.
My brother Jeff loved to watch me play this game. He called it Chwono Twigger. On our second playthrough, he made me name the characters after people he knew. So Chrono become Jeff, I think he named Frog after me, etc. When it came time to name the time machine, he only knew my friend's big gray truck, so we called the time machine "Truck" instead of Epoch. That made for some really funny lines.
