Cim, FFX-2 doesn't even have a game over screen. How was it possible for you to see it?

Anyways, first to mind?

FFI - the fifteen block game
FFII - Ming-Wu dies, Josef dies
FFIIIj - Onion Knights
FFIV - "Graham Cracker"
FFV - Atomos (no idea why)
FFVI - Celes suicide attempt
FFVII - Aeris dies
FFVIII - I got nothing for this
FFIX - "Ooo, soft!"
FFX - The Spring
FFX-2 - /wrists
FFXII - Cid receives 99999 from a 50 chain quickening and dies with about 2000 HP

Or game defining, as in what it set me up to expect? If so, then only a few games did I expect anything:

FFIIIj - ownage because of Onion and opening 5 lines
FFVII - emo, fleeing Midgar
FFX-2 - let the suck commence, real Emotion
