The new game +/encore mode is broken...
Before spending your money on expecting to do the same (as the game features list you can) you might want to know that instead of being able to start the game over- you end up starting your "new game+" before the final dungeon. If this doesnt bother you then i'de suggest waiting for a $10 copy from ebay; but if you bought this game for full price and played through the grueling hours of mediocre gameplay like i have- prepare to be disapointed.
The only good i got from finishing this game is that it made me dig up my old snes and copy of chrono trigger so i could enjoy a gaming era that could actually get things like the new game + feature right.
