Chrono Cross/Awesome
- The final showdown with Lynx/FATE.
- The "Save Marbule" sidequest definitely counts as well.
- Discovering the Frozen Flame in Chronopolis and speaking with Robo is pretty memorable, too -- not "awesome" as in "cool", per se, but the imagery, music, and information being conveyed to you at that moment are all pretty awe-inspiring.
- Successfully casting the Chrono Cross Element in the final battle with the Time Devourer.
