Fate/Extra is a turn-based dungeon-crawling RPG that takes place in a parallel universe in the world of Fate/stay night, with the world having gone down a very different route after a certain incident in the 1970s.
It was followed up by Fate/Extra CCC, which is not a sequel but an alternate route of Fate/Extra's main story.
There is unused dialogue tied to the now-scrapped ability for the player to save Rin, their opponent in Week 6 if they chose the Rani route earlier.

...Can I stand to lose her forever like this? There's no guarantee that I can save her.
Is it too simple of me to think that with my Command Seal I could?
If it fails, I will have wasted a Command Seal. But, even so-
> Use a Command Seal to save #C120200255Rin#CDEF.
Knowing there's a chance I could save her, I have to try. Otherwise I'd regret it the rest of my life.
As I hold her disappearing hand, I press the back of my hand...my Command Seal against hers.
I'm not sure if its possible to transplant Command Seals, and they're for controlling Servants anyway.
...But, I have a hunch. I'm not human like the other Masters. So maybe, if it's an anomaly like me-
[Rin]
...H-Huh? This is weird. Why am I feeling a surge of power...? W-Wha?! A Command Seal?!
Why is it on my hand...? Hey, let me see your hand! I knew it! Why did you use your Command Seal?!
And not one, but TWO of them?!
Only one Command Seal remains on my hand, tightly held in #C120200255Rin#CDEF's.
One of my Command Seals is on #C120200255Rin#CDEF's hand.
The other must have been consumed to facilitate the miracle.
[Rin]
What were you thinking?!
You never should have used your Command Seal right before your battle with #C120200255Leo#CDEF!
Did you tune out when I was telling you to defeat #C120200255Leo#CDEF?
Did you do this out of spite or something?! ...Ugh, what am I supposed to feel?
I didn't save her to get a thank you, but I didn't expect to be yelled at.
...Well, that's #C120200255Rin Tousaka#CDEF for you.
That the firebrand I wanted to save, even if it handicapped me against Leo.
[Rin]
...Oh well. If you want me to live so badly, what are you going to do about it now?
You didn't save me just so you could disappoint me, did you?
You should be able to trounce #C120200255Leo#CDEF without using a Command Seal, right?
...It'll be tough, but you can do it.
She looks away sheepishly.
...It makes me happy to hear words of appreciation out of her mouth, even if they are wry.
I know I did the right thing in saving her.
...Oh, and let me know as soon as the Holy Grail War is over, okay?
The Harways will be after you. Don't worry, I'll take care of you.
They're already after me anyway, so we'll be in the same boat.
You can depend on me. I'll protect you after this tournament is over, no matter what.
I tilt my head in puzzlement.
Not only is she sure I'll beat #C120200255Leo#CDEF, she's making plans for afterward.
I think she's getting way too ahead of herself-
[Rin]
Wh-What, isn't it the obvious thing to do?! And wipe that "Oh woe is me!" look off your face!
Helping another person is a big deal, right?! And of course you had to go and do just that!
To help another person is to take a certain amount of responsibility for their life!
Listen, it's a lot easier to stand by and watch someone die than to do something to keep them alive.
...I see. Such an act couldn't be done without compassion. And to save a life is to share in it.
All I can do now is prepare and face what comes. I only get this one chance at life.
Though saving a life is a great responsibility-
[Rin]
It's far better to save a life than take one. That's right. That's why I'll do everything I can to help you.
It's all I can do right now-
> Don't save #C120200255Rin#CDEF.
I'm hesitant to use my Command Seal on a gamble that may not pay off.
More importantly, even I was able to save her, I have a feeling she'd be none too happy about it.
Yeah, no doubt #C120200255Rin Tousaka#CDEF would
be pissed that I wasted a Command Seal before my showdown with #C120200255Leo#CDEF.
And so....there's nothing I can do right now other than stay by her side until the end.
There is unused dialogue tied to the now-scrapped player choice of saving Leo after defeating Gawain in Week 7.
According to the published game script in Fate/EXTRA MOON LOG:TYPEWRITER II, there were 3 unused endings for the game, one of which was for Leo. The player would have been able to unlock the ending if they had all 3 Command Spells when they defeated him and chose to use some to save him. He would have accompanied the protagonist to their confrontation with Twice, and they would have emailed the location of their original body to Leo, who would have used the Harway Foundation's resources to revive them.

It looks like there's a deep pain in his chest, as if his Command Seal is reacting to his heart.
Should I leave, knowing that #C120200255Leo#CDEF will disappear any moment now?
Whoever's it is, death is saddening.
If this boy were given the chance to rule the world, he'd do so with compassion now.
He'd be able to change society into something better.
The world is about to lose a potentially wonderful ruler. Is that right?
There's no guarantee that I'll be able to save him. But, if I use a Command Seal...
> Use a Command Seal to save Leo.
> Don't save Leo.
If this is the last fight, there's no reason to be frugal with my Command Seals.
I just can't stand to watch while he disintegrates.
I approach the disappearing boy and push my Command Seal against him.
And I wish-
Save this boy.
[Leo]
...This is...
A Command Seal comes off and the boy's body moves.
The rules of the Holy Grail state that those without a Command Seal will be eliminated.
Now that #C120200255Leo#CDEF has a new Command Seal, he's been given a new life.
All that's left on my hand is one of the Command Seals. Transplanting the one must have taken two.
[Leo]
...You saved me.
...The me from before could not have understood your actions at all. But now, I understand completely.
Humans make mistakes, even me, who was a failure of a human being.
...Still, you let me live. I will show you my gratitude not with words, but with my actions as king.
He swirls around and walks toward the exit.
The world will see him return, and he will fulfill his role as leader.
There's no need for him to play knight in this place for any longer.
While gazing at his spirited back, I also head to the exit. I have no business here either.
There is unused Japanese text with multiple instances of the narration referring to the Moon Cell as "Type Moon" (タイプ・ムーン, the alternate name for Crimson Moon from Tsukihime). This lines up with Studio BB developer interviews on their original plans for Fate/Extra.
